@@subetai17 yeah I probably did. Don’t know when to shut up do I. Time stamps available to jump to the interesting bits. Thanks for checking it out subetai appreciate it
@@subetai17 jog on I would of enjoyed a video double the length, no one in the comments agrees with you.It was a great video,I know a fair bit about the stid and didn't find it repetitive,annoying or anything like that.Its was great.
It's terrifying, particularly when it looks like a quaint little shallow stream which you could skinny dip in to cool off on a hot sunny day. I bet the Strid has lured thousands to their deaths over the centuries.
I use to be a sailor, (I don't know why) but water has always terrorfied me. You never know what's in it, or what the water hides until you get sucked into it. I don't trust any body of water.
The great lakes are like that. Since they're not salt water people don't think they're dangerous and every year some poor idiot washes up on a beach after falling from a pier or not realizing how very deadly the under tow is.
@@shanepatrick4534 happened a month ago in conneaut lake erie, people dont realize there's more shipwrecks and stuff on lake erie and the other lakes than any other body of water on the planet
@@shanepatrick4534 that’s how it used to be for locals like me around Mt. Hood between my experience of 1998-2010 when every year we would have a local news watch of at least 2-5 dead because they underrated the mountain and didn’t bring a GPS. It got to the point where as a child I would feel no pity at all. You respect the water. You respect the mountain... no matter the appearance.
@Thomas Shannon how is it bad..... do you know how amazing it would look down there............ you obviously have never had someone to show you the right way, except the right way of others. Still think if I had a different a not of live would have turned out diff if had my Millionaire always have always will
It’s basically an underwater water fall that pulls you into its basin of caves. Be safe and god bless you for making these videos, I’m sure your saving people with these videos
This is incredible. It is mind boggling to me that it goes that deep. If I were on top of a roof at 65 meters up. I'd have the shakes looking down. Yet people are just walking along the edge of the rocks like theres not a giant chasm below them. Funny how visuals work (meaning since we cant see it, it doesn't seem scary).
@@THISISLolesh if it's not that deep then where is the volume of the water? It's clearly not in the width of the river. It's geologically straightforward for it to be a flooded slot canyon with such depth.
I have never heard of The Strid before, and I found it absolutely fascinating! This is an exceptionally well made video and I loved the drone footage! I hail from Tampa, Florida, USA.
An interesting note to compare is The deepest section in the Niagara River is just below the Horse-Shoe Falls. It is deep as it equals the height of the falls above: 52 metres (170 ft.) , but as you determined the deepest part in the Strid is 65 meters (217ft). Jack - Thanks for the info on the Strid.
Makes sense that an underwater waterfall with that much pressure would get plenty deep too, they're often deeper than the result of a normal waterfall and that's not counting geological formations that existed before the river itself
Great comparison. I found this video that shows Horseshoe Falls and it's mind-boggling that The Strid Is DEEPER than the height of the falls 😮 ruclips.net/video/FeOEjiCMl1k/видео.html
That's terrifying hearing how deep this river suddenly drops on top of that you have to worry about rocks,caverns,and cold frigid water guess that's why most would have a zero percent chance of survival
Folks, please note that “The Strid” is just a small section of the River Wharfe, in Wharfedale, Yorkshire. It is not the River Strid which seems to be a source of confusion judging by many of the comments here. This interesting video was done when the water level was relatively low, but even I would think twice (and more) before trying to jump across its most dangerous parts. We live in Burley-in-Wharfedale, just a little downstream of the Strid and have visited it numerous times to photograph the area throughout the year as the season and water conditions change. There’s no doubting that in flood it looks particularly dangerous so it’s easy to appreciate the risks, but when it’s summertime it looks like a little stream with nothing to indicate the danger except for the numerous warning/danger notices in the area.
@@Vespyr_ Its probably all of the above alongside some other reasons, so I can’t claim to know the precise answer, but I do agree with your suggestions. If you walk upstream of the Strid the river Wharfe is quite a lot wider than than the Strid, and the same holds true for the downstream as well. It suggests that there’s more going on in the Strid for it to be narrowed on the surface. If The upstream water has to go somewhere to allow for the conditions we observe - the Strid’s surface water is considerably faster than the up/downstream area which would support your thoughts about speed/depth/turbulence, the latter being possibly the hardest bit to deal with. If you are in the area during spring to autumn after a local rainstorm has fallen upstream, the power of the water passing through the Strid, is quite an awesome sight. Unfortunately those that die trying to jump across the narrow parts tend to be tourists that ignore the warning signs and they only see a small stream that looks appealing to cool off in (yes, we do see sunshine in Yorkshire, lol), but they don’t appreciate just how strong the current/undertow/turbulence/depth is, nor do they appreciate the danger until too late. I suspect that as it’s in an area of limestone strata that, as with other limestone areas (the North Riding of Yorkshire has lots), that there’s plenty of underwater overhang’s, which, coupled with fast flow and turbulence, it’s going to make death by drowning far more likely (the turbulence/& associated bubbles won’t make it easy to swim to safety). Add in these possible complications and the likelihood of survival that much harder eg fast flow/overhang’s water power making impacting the head on the rocks highly likely. When a body is recovered, usually a bit further downstream, it’s difficult to assess the precise cause due to all the marks, bruises and extensive damage, resulting in it being listed as “death by drowning”. Sorry for the length of my comment but hopefully it helps with understanding the situation? I didn’t want to just answer your question with some trite response such as “a combo of all of the above plus drowning” as it doesn’t help. It’s a pity that there’s no way to add photos/videos to accompany a comment as I’m sure it would show both the beauty of the area alongside the hidden danger of the area!
@@Vespyr_ Just spotted that Jack a Snacks has released a couple of newer Strid videos, and there’s one RUclipsr (MrBallen) that’s watching! Already hooked on these new videos which, TBH, show some of the reasons why jumping/swimming in the Strid is a shoe in for those that would like a posthumous Darwin Award!
@@Vespyr_ If underneath looks anything like slot canyons the danger is a hidden blender ready to bash you against the walls with highly turbulent waters until you're a nice puree.
@@captainsquiggles5958 Basically a metre is equivalent to 3ft 3 inches. So times by 3 - and if it's a big number add on a bit for every set of 3" making up another foot. So 4 metres = 13 feet. (I'm British and we think in both metres and feet and inches).
I could imagine being tumbled around like a washing machine underwater and having no idea what way is up. With 60 meters of water with dark water, cave systems, bubbles everywhere, etc..No wonder people can easily drown there. You can kick and swim as hard as you want and it's useless without a sense of direction.
The way to find which way is up is by blowing out air and seeing where it goes...but in the dark and with so many other bubbles I doubt that'd be possible.
It's not just that, the water is so turbulent that it essentially doesn't act like water. The turbulent nature of it adds a ridiculous amount of air bubbles to the water and you can't float in air. You essentially sink or fall to the bottom due to the nature of this effect.
@@VenomGamingCenter I'm not a professional rescue diver to give answers on how they do what they do exactly, but if people lose their lives in a certain river or stream, most likely someone has attempted to dive it to recover the body...We have a river near my house that regularly claims lives of people falling in or kayaking, swimmers, etc..and the volunteer fire department dive it to do body recovering. In certain spots you see vortexs' and undertoe currents usually after the small waterfall that does the most damage and holds people underwater...I don't know how they overcome these features but I do know that they dive it and recover body's regularly.
It's a scary feeling to be sure. I was knocked off a tube and dragged underwater in a river where I live and was caught in a small turbulent area under a low tree branch like that. And when I was able to find the surface again, there was so much debris from everyone's stuff always falling into the river and getting caught in the branch that I couldn't push it all aside and get my head above water. Very lucky I was able to finally get out. 0 out of 10 experience. Be careful in and around water.
Deeper in there's zero visibility in cavernous areas. The water is dark and foaming like what I see in Scotland - runoff from peat bogs. Undertows and vortexes, a pure nightmare.
Sonars work with sounds waves reflected from the bottom. Sound moves ~3x faster in water than air so with how much air there is in the water, it would slow the reflection of the sound waves down a bit and would trick the sonar into reading the water as deeper than it is. It’s still incredibly deep and dangerous but the numbers will be skewed a little bit towards the deeper with more bubbles present. I love the video and how you put it together, just felt like sharing this lil bit of info
I thought about this too. I know that subs used to hide from Sonar because of varying temperatures being unable to detect there presence. I wonder if that would apply here?
If it is an underwater sonar, which I assume it is, then it’s safe to say that the calculation for depth accounts for sound travelling through water. It might actually be inaccurate used in air as it calculates a slower sound travel in air as it does for water.
Sonar doesn't work well in very turbulent water. When you're on a boat and going at speed, you cant use it due to the turbulence and air bubbles in the water. I'm not sure your max depth readings are accurate because of that
That is true, we also know it's not that deep. I believe that it was properly surveyed back in 1981 by University of Leeds divers. The depth is only between 20 ft (6m at low flow) up to a max of 9m 30ft at high flow.
@@HoleyMoleyAlex A lot of erosion can happen within 40 years with the flow that water has. Not only that, but it's an entire cave system underneath that makes it too dangerous to get into - even for divers.
Holy balls! That's one deep stream. We have a few of those here in Sweden too. Say the stream is 1 meter wide and 66 meters deep. That is more volume per second than my 60 ton truck of gasoline/diesel. Truck was 18-21 cubic meters plus 33 cubic meters for the trailer. That thin/deep river flows more than a fully loaded tanker truck measuring 25 meters long 60 tons! Just wow! Great job!
I think you will find some of those deeper sections have regions of slow flowing water within them. This usually happens when water flows over a depression that is deeper than its deepest outlet goes. You essentially end up fairly stagnant water at the bottom being trapped by the rise up to the outlet acting like a dam so most of the flow occurs at the top above the outlet height.
After hearing Mr. Ballen's description of this part of the river, my anxiety was through the roof watching you work your way to the edge. People have slipped on the rocks and fallen in. This has got to be one of the most terrifying places in nature...
I watched my brother drown in a slow looking river..under currents got him, he’s a great swimmer and strong but the river just took him away…he popped out eventually not far away, we actually brought him back, he was so lucky. Please be careful folks around any river.
For us visual types: The deepest part could fit 4 school buses stacked end to end, or you could submerge the entire Leaning Tower of Pisa into that part of The Strid, and still have room to spare. 😳
Oh my God! I was so nervous for you going so near that water. It looks like there should be all kinds of warning signs and alarms. So, scary. My heart is actually beating faster watching your approach.
@ᅠᅠ yeah there is a section of river that's a feeder to the lake Michigan that is electrified by the US Army Engineering Core to keep an invasive fish out, but to be fair that section is concrete and well signposted that it's electrified. Cost in the high hundreds of millions to build and maintain
Try looking up Bolton Abbey stepping stones. You'll see the exact same river, about a mile down stream from The Strid. 60 stepping stones to cross the river.
Fun fact: The Congo River discharges the second highest amount of water in the world, yet it's only the 9th longest. The river reaches a depth of 720 feet (219 meters). For comparison, the Amazon reaches a max depth of 328 feet (100 meters) and the Mississippi is about as deep as the deepest part of the Strid (200 feet, or 60 meters). The Congo is so deep, it has gouged out a deep underwater canyon into continental shelf under the Atlantic Ocean at its mouth. The Strid is like a mini Congo, except much deadlier.
Ever since I heard of the strid I asked myself "why hasn't anyone put a sonar on a stick down there?" You sir, have solved one of the longest lingering question I had.
Stuff like this exists all over Canada just not as dramatically. Our old farm had a river that ran through it and fed a dozen more properties. It was 4-5 foot wide in some places yet moved millions of tons of water. Some sections were 35+ foot deep. We lost entire cattle into that damn river more then once. Just Fing gone. And we have pulled Sturgeon out well over 150lbs There is also a truck down there somewhere.
it’s a mind boggling piece of river, I was a paramedic and a member of the fell rescue who searched for them unfortunate newly weds, it was so sad, I would think that one of them slipped on the limestone and the other tried to rescue them. They found them down stream near addingham.
Jim thats really cool, do you remember much about that event? I haven't met anyone that was part of that. Would you by chance be willing to maybe explain to me what you remember happening and what you were doing whilst part of the search party? I'm sure there are lots of people would love to hear that story. Can be done over email rather than comments if want to :) No worries if you don't fancy it though!
@@jackasnacks it happened in aug 1998, it had been raining very heavy. We parked at Barden bridge up stream from the strid woods, I was amazed at the volume of water in the river. The wharfe like most of the Dale’s rivers are spate rivers, they rise and fall very fast especially in the summer. We searched down stream to the bridge at the A59, alas no sign of the two was found. Lynne’s body was found on the weir at Addingham 6 days latter, Barry was found on October 16 10 miles downstream. I’m glad for the family and friends that they recovered them. They either slipped in or got caught in a flash flood. There’s not much to do when a person gets caught in there. One thing that I do remember of the day is, when I got back to my vehicle someone had smashed my car window and stole my child seat and various other items of property. Stay safe. It was a good video that you did and the one with the GoPro 👍
Having grown up in Yorkshire, with grandparents nearby, and therefore having visited the Strid many times, I have always felt an overwhelming anxiety even looking at pictures of it, and a healthy soul gripping fear of it. Thanks to this incredible and informative video, I no longer have that fear, which has been replaced with a much more rational absolute terror of otherworldly why-would-a good-and-caring-god-create-such horror proportion. Good job, Jack! 65 meters. Fucking hell.
Maybe He created it to teach us to show caution no matter how serene something looks . To always practice safety , to highten the self-survival instinct we all possess
@@MrSpruce - " And most importantly , to lure children to their deaths " ? Are you freakin serious ? I make a simple " maybe " comment and an atheist troll tells us God lures children to their death .. Get a grip dude and take your Meds .
This thing is so terrifying. Imagine you're out with a friend or someone, and you're walking, and your friend is like "Just let me walk across this little stream quick" and then they just vanish? You'd lose your mind.
Lots more people will die in the next few years as they progressively lose the ability to judge or even think about their surroundings and what is happening. Zombies are here.
Usually the fatality rates (for anything from car accidents to skydiving accidents) are based on deaths vs accidents happened during the activity or in a certain place, rather than deaths vs people there or doing the activity :^) but yea that guy has balls of steel! wtfff
@@noaburke3704: Well, an "accident" that goes as far as being recorded as a statistic there would pretty much be limited to fatalities. They don't keep stats on scraped knees.
When I was a kid on the River strid, there was no darkness greater than the hearts of those who hid, below the abbey in caves of cold, the dragon they fed, he who eats must be fed, those who feed the enemy have run low on souls, beware the caves of cold beside the River strid that run beneath the abbey beyond the wharfe of Bolton Priory. 2 sticks will show the way echos the hearth. I will return again one day and free those that were lost, When I was a kid on the River strid
I haven't been trained in sonar but I would have to imagine that if you had a better mount for that thing you would get a more accurate reading. The current looks like it's pulling it at an angle which I would imagine would distort your reading some what. I mean it's still crazy deep
I would agree with you on this here, as far as sonar goes i would say that one would not be to accurate in those conditions ? needs to be a fixed transducer on a ridged out rigger !!, 210ft seems a bit excessive to me, we have the Lune deeps out of Fleetwood with a max depth of approx 230ft and that gets billions of cubic mtrs of water through it twice a day running at 7 knotts which is just over 8mph,
Nothing he did was accurate. The sonar needs to sit level. Not at a single point was it level. He kept it tight on the pole, not loose as it is supposed to be. Soon as it is angled it bounces back on an angle. Essentially it is 100% inaccurate.
I agree, its no way near a scientific measuring. I have an exact same sonar at home. Though you can have in an arm on a boat, but much more stable then this setup.
@@natehale1982 yeah I had no idea what type of sonar device it is or anything for all I knew it has some internal self leveling system. But I figured that the chances of that are slim and the fact the current was ripping it sideways meant it would fuck it up if it didn't lol
I had asked about it in the other video but the drone footage was really helpful in explaining just why the Strid is so unusual - flipped upside down is an apt description indeed! It’s essentially a slot canyon carved into the relatively soft rock as it drops from the heights above. Gravity never sleeps, and water never stops working either, you know. There’s several local watercourses here in the Ozarks that have their own quirks, attractions and potential hazards too. One I haven’t really found a lot of good information on is just exactly where is the deepest known location on Table Rock Lake. Most people say it’s the river channel just above the dam, but I’m inclined to suspect it’s a potential blue hole (called a calyx) on the outer left edge of a right hand hairpin bend just below the Kimberling Bridge. The channel is generally 200-220’ here but some charts have indicated 270-280.’ Whatever the case, it’s reasonable to assume it’s substantially deeper than usual due to the sharp bend creating a local whirlpool effect and scouring the bottom out at the base of a sheer underwater cliff. There are several such locations along the lake but this one is the deepest.
Now that you've said this, I regret ever swimming in Taneycomo, because the surface looks like this strid does when the strid is calm, and I already had to climb down a cliff to swim in it in the first place and it was COLD so it know it came from deep. I shudder at the thought.
Great video just dont get so close without being tied to something. I was near there just yesterday evening at sunset and you can hear rocks being thrown around in the strid. freaky sound.
This is a great video! I visited the Strid once and stood on the rock where it would seem possible to jump down on the lower one on the other side..... I was told that many have tried over many centuries and fallen in, never to be found again! I am amazed its 65m deep! the turbulent currents must be immense. Thank you for measuring the depth, a job well done.
Yeah that rock in the middle is about half way up the Strid. The day i filmed this a young guy actually jumped to it. You can see him stood on it in one of the drone shots although my drone was fairly high at the time. I considered doing the same but i just didnt have thee confidence to do it lol
@@jackasnacks I watched from New Hampshire too, but I'm from West Yorkshire and lived pretty much on the banks of the Wharfe. crazy! It's Wor-fe. To rhyme with "war"
That's the depth that the sonar picked up from directly below. You could have been reading the depth of an underwater shelf or overhang at 60m but the bottom could be much further down than that. It's a mind blowing thought.
Ive been to the strid many times...it amazes me how anyone could want to stand near the edge. There is a strange feeling looking into that murky water, knowing the sheer force running underneath. I always wondered why no one built a bridge over it. I do believe this river is easily 30m deep but not 60......regardless, you have made an excellent video and i hope some of the mysteries of this place will be finally revealed. I heard somewhere over 1000 people have died there 😵
It's been about forty years since I visited here. I remember swimming in the wider section and then walking up with the family to the falls section. I knew it was dangerous, but seeing your readings, just makes me think as to how powerful it is! I seem to recall seeing some names carved into the rock around the falls section of victims and there had only recently been a fatality (this would have been around 1982) so it was quite sobering, even for the eleven/twelve year old me. A beautiful part of the world but oh so deadly if you were careless. Thanks for bringing back some childhood memories.
My uncle Sid use to jump over the rocks with me in his arms over sixty yrs ago he was an athlete,but I wouldn,t recommend , it's a stunning places to visit.
ur parents should be fired for allowing u to go there. But then again ur british , dont they start giving you vodka straight out the bottle around age 8 or 9?
I’ve been swimming there as well. I remember there was always talk of the people that recently died. As long as you’re careful and swim strongly, you will be ok.
Wait a minute, if the source of sonar beam is not pointing straight down you will get false depth reading. If you hold the ball like you did, it will aim diagonally and resulting measurement will be off quite a lot. The correct way would be to let the device float freely in the current and take some path along the stream. Though turbulent water will still cause some deviation but you will get much more precise figures.
Quite aside from the fascination surrounding the Strid, I'd love to visit this part of the Yorkshire Dales, what a beautiful bit of country. Cool video, thanks for making it!
I wonder if the turbulence is rotating the ball so it it measures slightly diagonally (away from vertical) or if the frothy bubbles do anything to the sound waves?…. Certainly staggering shape of a channel!! Thanks for giving this a go, wonder what other super deep river channels there are?
Bolton Abbey was one of my go to places when I wanted the serenity of walking British history and getting tea. The tea shop nearby was one of the best. Fountains Abbey was my absolute favorite. 1985-1990…loved every second living in England.
I think you went a bit close just to take a depth reading but such an interesting video, this kind of content wasn't available when I was doing research on the Strid earlier this year. You legend!
Omlg it will suck you in like a demon it will a hand will reach out and suck you down you will never recover you should really cover yourself in bubble wrap and chain yourself to the floor in your house its the only positive way to be safe oh yeah also make sure to cover yourself in hand sanitizer to avoid the super scary reset cervesa sickness because you might get pulled in the river and die from corina.
I mean he knows how how swim right? Even if he fell I'm sure he'd be fine just swimming back out. The danger comes when there's flooding and the river current is moving too quickly.
@@miked815 actually the problem is the water is so turbulent it becomes aerated and anything that falls in sinks to the bottom. Theres no swimming out of the strid!
Been waiting for someone to do this for YEARS!!! Legendary!!!! Please be careful though. The strid is no joke (as you know) and you seemed to get fairly close the edges!
Great place many quality days spent here, surprised by some of your findings. Deadly water in parts my heart gos out to anyone who's lost a family member to this river. Stay safe if visiting 👍
all i could think about while watching is just how beautiful that area is, the greenery of the trees with the turbulent water in the background gorgeous!
Very interesting. Worried you're putting yourself at risk. Is it possible that the sonar ball is dragged to be at an angle from the point of suspension so maybe you're measuring a diagonal distance rather than vertical?
Depending on the rising air bubbles your sonar may not be getting accurate signals. Good videos, crazy to think that it's over 150 feet deep. Also crazy to think that that ledge you are standing on has about 10 feet of rock and underneath is near 200 feet of water.. would be cool to test how far under those ledges is void till it hits am actual bank wall :)
Yeah my thoughts exactly - the speed of sound in aerated water is likely to be much lower and give erroneously high depth readings. It didn't seem like he calibrated with a reference depth in the turbulent water or anything? Not the best science process but still a fun video I guess.
I gave a like, which is getting rare these days because of the amount of content good vs bad.. But that the author asked in a genuine way and explained why. Then off course such a small gesture will be granted. Absolutely. That it's a interesting video about something that scary, is just a lovely treat
Really interesting video, my girlfriend’s folk live at Bolton Abbey, I can’t wait to tell them! We knew it was deep, but nearly 70m! Wow. They say the ‘Strid’ gobbles you up, but you may never surface! Think you proved exactly why that’s the case! Great video! You Sir, have my subscription!
Christ, just watching a few of your other videos! The branches, ledges and undercurrents you filmed at around 30m made my skin crawl! I honestly got goose bumps! I think it might be that you can kind of image you could swim (float) down the length of it. It seems so innocuous. Then the reality of the thought kicks you in the behind! If you went in (not to labour the point) but I think it would be like an underwater maze of ledges and you’d never find the surface again! Enough of that now though. But great series of films, thanks for posting!
Never heard of this place before, but I can certainly see it's really dangerous and deep. No wonder people get caught in that current and get bashed to death. Be safe. US 🇺🇸 California.
I'm thinking that the ball the sonar is on is getting tilted by the force of the water. This means you're likely reading the depth at an angle. It is still insanely deep, but I don't trust the accuracy. Quite cool. Thanks for the effort you put into this!
On the two models of Deepers that I've seen, the actual transducer is gyroscopically mounted inside the casing, with ballast. So no matter the orientation of the outer case, pings are directed straight down.
@@QuantumLeap83 All of the information I've read and researched says different. If you have photo's of the internals with gyroscope mount/chip or link showing either one I would be interested. I looked at buying one but didn't because they didn't have a gyroscope in them. No flame just genuinely interested in finding out.
This reminds me of about a year ago we were visiting the Kootenays in British Columbia going on a hike, and we were walking along this little stream, just about wide enough to step over. We saw some ducks on the other side, so my dad picked up my little sister (7) and went to bring her across, but he fell in and it was suprisingly over 6 feet deep with a crazy strong current! Unfortunately there was a death My dad's phone was absolutely soaked and i think it broke And i thought that was deep!! Crazy how deep these little cracks or rivers are
I lived in a 21-story high-rise dormitory for college and I just googled the height of it and it's shorter than the strid is deep according to your readings
Thank you for the experiment! I search this information everywhere, glad some one test it and share! Really amazing! Good video! I will sub to your channel! Be careful! Hugs from Brazil!
To put this into perspective, the UK's tallest roller coaster "The big one" is 65 meters tall. That's kinda scary deep. en.wikipedia.org/wiki/The_Big_One_(roller_coaster)
I've dived the River Etive in Scotland which is very deep and narrow in sections. It goes fro 2-3m down to 15m. The current in the deep sections isn't bad as the flow isn't as constricted. Still an exiting drift dive with lots of overhangs and caves. In the shallower sections it's a bit like a washing machine ;-)
Great video. All the others focus on the tragedies - this one has a charming pastoral sensibility. Just nature being nature - and your adorable sense of discovery. Love it.
I saw an article that claimed the Strid was only 30' deep. Apparently some scuba divers had been in it before it was closed to diving in the '70s. One way to check this out is to measure the flow of the River Wharfe and calculate what volume the Strid would need to be to handle all that water passing through it. We know how wide the Strid is, so it should be easy enough to determine its necessary depth.
This assumes you know the speed the water is travelling which we just dont. you could measure surface speeds but even then things like turbulence makes it difficult
The way water forces through there it may have been a correct reading in the 70's and this one may be correct now. It's shocking how many tons water can shift.
It doesn't appear to be anything approximating a rectangular section down there - there seem to be a lot of caves and holes so even knowing the volume may not get you the right depth, which is insane
@@tricky1992000 There is absolutely no way ~180' of rock was eroded in 50 years. No way. Water erosion on that scale would take hundreds of thousands or millions of years.
Cheers Ben good to see you here mate. Enjoyed your fell walk in the dark video really good idea that one. Hard to get the lighting right for viewers but you done a good job with the photography was awesome to see
Curiosity is enough so i am going back with another test this week. Going to try and get some under water footage this time so if you're interested be sure to look out for the next upload! Thanks for the comment though love the strid community
I've always had a fascination with the Strid. As far as I know, there isn't any footage from under the surface, so you would be a first. Not sure how easy it would be, but setting up a cross frame across the Strid to allow a GoPro to be dropped by a boom on a 10 meter pole might show a decent view of the rock undercutting
As you mentioned that the bank is actually an overhang with cave systems underneath, could it be you're measuring the walls of cavities hollowed out by the turbulence? I can imagine that the sonar ball is not always 'looking' straight down. Nevertheless, amazing sizes in relation to the width of the Strid! Nice video. I 'Thumbed up'
As Bolton Abbey ruins are a favourite day out and school trip destination a walk to the strid tends to be part of the day. Im amazed there arent more deaths.
To put this in perspective for people who have played minecraft: the ravines in that game are about 40 meters deep. This is more than one and a half times that. In fact, the normal water surface level in the game is 62, so this is about as deep as a drop all the way from the surface to Y=0.
Great video, thanks for introducing me to the Strid. I was skeptical of the 100% fatality rate, but 65+ meters deep?! That's 195 feet! On a river maybe 10-15 feet wide? Incredible.
That particular section is only about 4-5ft across due to the way the rocks cover the majority of the top, that’s why it’s so scary, people often want to jump across, but one slip.. you can be pulled down due to the undercurrent, quickly end up under those rocks and get smashed about in the area below 😕
I’ve recently heard about this place and is fascinating and scary. Cool to see someone investigate it . Cool video. I wonder if at one time it was around 30 m deep but since the water is funneled and moving so fast there,that it erodes the rock much faster?
Yes, that's partially the case. It is highly probable than the rock in the walls of the river endures more against the erosive force of the water, so it gets deeper instead of wider
Hello from Kansas City, Missouri, USA. Absolutely terrifying stretch of river. I'm so glad you made the video without being harmed. In the States, people are so litigation conscious that a dangerous stretch of water like that would be cordoned off and covered in Danger signs.
Well done, sir! Thank you for doing something no one has done. That is crazy deep. PLEASE, don't get closer. I was stressed watching you try to get the depth at the 65m mark. I would need a rope tied on to go to that point.
In the past, I've stepped into a pair of Simms and fly fished in N. GA a lot... but I'll never look at another trout stream in quite the same way anymore !!
I feel a great disturbance in the Force, as if millions of professional marine geophysicists cried out in agony… Looking at the numbers and the channel conditions (esp the bubbles & turbulence), I think you’re getting a few erroneous measurements. Probably better off with a mock-up leadline? Need 50m of rope, a very heavy weight, a tape measure and patience to tie a load of knots at 1m intervals ;) Great to see someone interested in investigating the depths though. Fascinating world, underwater.
@@ThorRuneHansen I would imagine there's a pretty consistent aeration of the water in the turbulent areas, so it seems like a steady, but probably wildly inaccurate measurement is likely.
Just saw this after I posted a comment, air entrained in the water would throw off the readings a lot. The speed of sound in air is a lot lower than it is in water and could give readings showing a greater depth than there actually is.

You'd have to weight it down a bit, and keep it on a chain as you lower it so you can 'steer it' into the deep waters before it gets washed away.

Indeed it is.
It's terrifying, particularly when it looks like a quaint little shallow stream which you could skinny dip in to cool off on a hot sunny day. I bet the Strid has lured thousands to their deaths over the centuries.
I use to be a sailor, (I don't know why) but water has always terrorfied me. You never know what's in it, or what the water hides until you get sucked into it. I don't trust any body of water.
The great lakes are like that. Since they're not salt water people don't think they're dangerous and every year some poor idiot washes up on a beach after falling from a pier or not realizing how very deadly the under tow is.

This is incredible. It is mind boggling to me that it goes that deep. If I were on top of a roof at 65 meters up. I'd have the shakes looking down. Yet people are just walking along the edge of the rocks like theres not a giant chasm below them. Funny how visuals work (meaning since we cant see it, it doesn't seem scary).
It’s unlikely to be that deep, inaccurate readings.

@@THISISLolesh if it's not that deep then where is the volume of the water? It's clearly not in the width of the river. It's geologically straightforward for it to be a flooded slot canyon with such depth.
@@wilsonov87 Except that the river has overhangs, so it's not as narrow as it looks. It gets wider underground.

An interesting note to compare is The deepest section in the Niagara River is just below the Horse-Shoe Falls. It is deep as it equals the height of the falls above: 52 metres (170 ft.) , but as you determined the deepest part in the Strid is 65 meters (217ft). Jack - Thanks for the info on the Strid.
Makes sense that an underwater waterfall with that much pressure would get plenty deep too, they're often deeper than the result of a normal waterfall and that's not counting geological formations that existed before the river itself
Great comparison. I found this video that shows Horseshoe Falls and it's mind-boggling that The Strid Is DEEPER than the height of the falls 😮 ruclips.net/video/FeOEjiCMl1k/видео.html

That's terrifying hearing how deep this river suddenly drops on top of that you have to worry about rocks,caverns,and cold frigid water guess that's why most would have a zero percent chance of survival
Folks, please note that “The Strid” is just a small section of the River Wharfe, in Wharfedale, Yorkshire. It is not the River Strid which seems to be a source of confusion judging by many of the comments here. This interesting video was done when the water level was relatively low, but even I would think twice (and more) before trying to jump across its most dangerous parts.
We live in Burley-in-Wharfedale, just a little downstream of the Strid and have visited it numerous times to photograph the area throughout the year as the season and water conditions change. There’s no doubting that in flood it looks particularly dangerous so it’s easy to appreciate the risks, but when it’s summertime it looks like a little stream with nothing to indicate the danger except for the numerous warning/danger notices in the area.
What is the actual danger though? Will it suck you under? Is it just fast currents? Steep drops? What is it that kills you?
@@Vespyr_ Its probably all of the above alongside some other reasons, so I can’t claim to know the precise answer, but I do agree with your suggestions. If you walk upstream of the Strid the river Wharfe is quite a lot wider than than the Strid, and the same holds true for the downstream as well. It suggests that there’s more going on in the Strid for it to be narrowed on the surface.
If The upstream water has to go somewhere to allow for the conditions we observe - the Strid’s surface water is considerably faster than the up/downstream area which would support your thoughts about speed/depth/turbulence, the latter being possibly the hardest bit to deal with.
If you are in the area during spring to autumn after a local rainstorm has fallen upstream, the power of the water passing through the Strid, is quite an awesome sight. Unfortunately those that die trying to jump across the narrow parts tend to be tourists that ignore the warning signs and they only see a small stream that looks appealing to cool off in (yes, we do see sunshine in Yorkshire, lol), but they don’t appreciate just how strong the current/undertow/turbulence/depth is, nor do they appreciate the danger until too late.
I suspect that as it’s in an area of limestone strata that, as with other limestone areas (the North Riding of Yorkshire has lots), that there’s plenty of underwater overhang’s, which, coupled with fast flow and turbulence, it’s going to make death by drowning far more likely (the turbulence/& associated bubbles won’t make it easy to swim to safety).
Add in these possible complications and the likelihood of survival that much harder eg fast flow/overhang’s water power making impacting the head on the rocks highly likely.
When a body is recovered, usually a bit further downstream, it’s difficult to assess the precise cause due to all the marks, bruises and extensive damage, resulting in it being listed as “death by drowning”.
Sorry for the length of my comment but hopefully it helps with understanding the situation? I didn’t want to just answer your question with some trite response such as “a combo of all of the above plus drowning” as it doesn’t help. It’s a pity that there’s no way to add photos/videos to accompany a comment as I’m sure it would show both the beauty of the area alongside the hidden danger of the area!
@@Vespyr_ Just spotted that Jack a Snacks has released a couple of newer Strid videos, and there’s one RUclipsr (MrBallen) that’s watching! Already hooked on these new videos which, TBH, show some of the reasons why jumping/swimming in the Strid is a shoe in for those that would like a posthumous Darwin Award!
@@Vespyr_ If underneath looks anything like slot canyons the danger is a hidden blender ready to bash you against the walls with highly turbulent waters until you're a nice puree.
I find it strange people don't watch the video then comment about it based on the title. He even comments during the video that it's the river Wharfe.

@@captainsquiggles5958 Me, too, but I've spent so much time overseas, I can go back-and-forth between Imperial and Metric measures pretty easily.
@@captainsquiggles5958 Basically a metre is equivalent to 3ft 3 inches. So times by 3 - and if it's a big number add on a bit for every set of 3" making up another foot. So 4 metres = 13 feet. (I'm British and we think in both metres and feet and inches).

I could imagine being tumbled around like a washing machine underwater and having no idea what way is up. With 60 meters of water with dark water, cave systems, bubbles everywhere, etc..No wonder people can easily drown there. You can kick and swim as hard as you want and it's useless without a sense of direction.
The way to find which way is up is by blowing out air and seeing where it goes...but in the dark and with so many other bubbles I doubt that'd be possible.
It's not just that, the water is so turbulent that it essentially doesn't act like water.
The turbulent nature of it adds a ridiculous amount of air bubbles to the water and you can't float in air. You essentially sink or fall to the bottom due to the nature of this effect.
@@VenomGamingCenter I'm not a professional rescue diver to give answers on how they do what they do exactly, but if people lose their lives in a certain river or stream, most likely someone has attempted to dive it to recover the body...We have a river near my house that regularly claims lives of people falling in or kayaking, swimmers, etc..and the volunteer fire department dive it to do body recovering. In certain spots you see vortexs' and undertoe currents usually after the small waterfall that does the most damage and holds people underwater...I don't know how they overcome these features but I do know that they dive it and recover body's regularly.
It's a scary feeling to be sure. I was knocked off a tube and dragged underwater in a river where I live and was caught in a small turbulent area under a low tree branch like that. And when I was able to find the surface again, there was so much debris from everyone's stuff always falling into the river and getting caught in the branch that I couldn't push it all aside and get my head above water. Very lucky I was able to finally get out. 0 out of 10 experience. Be careful in and around water.
Deeper in there's zero visibility in cavernous areas. The water is dark and foaming like what I see in Scotland - runoff from peat bogs. Undertows and vortexes, a pure nightmare.
Sonars work with sounds waves reflected from the bottom. Sound moves ~3x faster in water than air so with how much air there is in the water, it would slow the reflection of the sound waves down a bit and would trick the sonar into reading the water as deeper than it is. It’s still incredibly deep and dangerous but the numbers will be skewed a little bit towards the deeper with more bubbles present. I love the video and how you put it together, just felt like sharing this lil bit of info
I thought about this too. I know that subs used to hide from Sonar because of varying temperatures being unable to detect there presence. I wonder if that would apply here?
I like how this comment was informative without sounding rude.
The algorithm used by the software does a good job at compensating for what you are describing as well as particulate interference.
The bubbles are only in the top meter. It shouldn’t affect it too much, but I’m wary of his results.
If it is an underwater sonar, which I assume it is, then it’s safe to say that the calculation for depth accounts for sound travelling through water. It might actually be inaccurate used in air as it calculates a slower sound travel in air as it does for water.
Sonar doesn't work well in very turbulent water. When you're on a boat and going at speed, you cant use it due to the turbulence and air bubbles in the water. I'm not sure your max depth readings are accurate because of that
That is true, we also know it's not that deep. I believe that it was properly surveyed back in 1981 by University of Leeds divers. The depth is only between 20 ft (6m at low flow) up to a max of 9m 30ft at high flow.
@@HoleyMoleyAlex A lot of erosion can happen within 40 years with the flow that water has. Not only that, but it's an entire cave system underneath that makes it too dangerous to get into - even for divers.
@@HoleyMoleyAlex I doubt the Uni of Leeds would have allowed it's divers to swim in the deeper areas, way too dangerous.
@@ApocalypticChronicles Eroison of solid limestone is not that quick, and they were cave divers are mad, and this was done by cave divers.

Holy balls! That's one deep stream. We have a few of those here in Sweden too.
Say the stream is 1 meter wide and 66 meters deep. That is more volume per second than my 60 ton truck of gasoline/diesel. Truck was 18-21 cubic meters plus 33 cubic meters for the trailer.
That thin/deep river flows more than a fully loaded tanker truck measuring 25 meters long 60 tons! Just wow!
Great job!
Thats a crazy comparison Kaxlon thanks for sharing :)
I think you will find some of those deeper sections have regions of slow flowing water within them. This usually happens when water flows over a depression that is deeper than its deepest outlet goes. You essentially end up fairly stagnant water at the bottom being trapped by the rise up to the outlet acting like a dam so most of the flow occurs at the top above the outlet height.
What is those here in Sweden called? Know any of them by name :D?

Fun fact: The Congo River discharges the second highest amount of water in the world, yet it's only the 9th longest. The river reaches a depth of 720 feet (219 meters). For comparison, the Amazon reaches a max depth of 328 feet (100 meters) and the Mississippi is about as deep as the deepest part of the Strid (200 feet, or 60 meters).
The Congo is so deep, it has gouged out a deep underwater canyon into continental shelf under the Atlantic Ocean at its mouth.

I haven't been trained in sonar but I would have to imagine that if you had a better mount for that thing you would get a more accurate reading. The current looks like it's pulling it at an angle which I would imagine would distort your reading some what. I mean it's still crazy deep
I would agree with you on this here, as far as sonar goes i would say that one would not be to accurate in those conditions ? needs to be a fixed transducer on a ridged out rigger !!, 210ft seems a bit excessive to me, we have the Lune deeps out of Fleetwood with a max depth of approx 230ft and that gets billions of cubic mtrs of water through it twice a day running at 7 knotts which is just over 8mph,
Nothing he did was accurate. The sonar needs to sit level. Not at a single point was it level. He kept it tight on the pole, not loose as it is supposed to be. Soon as it is angled it bounces back on an angle. Essentially it is 100% inaccurate.
I agree, its no way near a scientific measuring. I have an exact same sonar at home. Though you can have in an arm on a boat, but much more stable then this setup.
It’s just click bait
@@natehale1982 yeah I had no idea what type of sonar device it is or anything for all I knew it has some internal self leveling system. But I figured that the chances of that are slim and the fact the current was ripping it sideways meant it would fuck it up if it didn't lol
Amazing. I imagine standing atop skyscrapers in a dense city, with water flooding the narrow alleys almost to the top!
I had asked about it in the other video but the drone footage was really helpful in explaining just why the Strid is so unusual - flipped upside down is an apt description indeed! It’s essentially a slot canyon carved into the relatively soft rock as it drops from the heights above. Gravity never sleeps, and water never stops working either, you know.
There’s several local watercourses here in the Ozarks that have their own quirks, attractions and potential hazards too. One I haven’t really found a lot of good information on is just exactly where is the deepest known location on Table Rock Lake. Most people say it’s the river channel just above the dam, but I’m inclined to suspect it’s a potential blue hole (called a calyx) on the outer left edge of a right hand hairpin bend just below the Kimberling Bridge. The channel is generally 200-220’ here but some charts have indicated 270-280.’ Whatever the case, it’s reasonable to assume it’s substantially deeper than usual due to the sharp bend creating a local whirlpool effect and scouring the bottom out at the base of a sheer underwater cliff. There are several such locations along the lake but this one is the deepest.
Now that you've said this, I regret ever swimming in Taneycomo, because the surface looks like this strid does when the strid is calm, and I already had to climb down a cliff to swim in it in the first place and it was COLD so it know it came from deep. I shudder at the thought.
Great video just dont get so close without being tied to something. I was near there just yesterday evening at sunset and you can hear rocks being thrown around in the strid. freaky sound.
Wow!
This is a great video! I visited the Strid once and stood on the rock where it would seem possible to jump down on the lower one on the other side..... I was told that many have tried over many centuries and fallen in, never to be found again!
I am amazed its 65m deep! the turbulent currents must be immense.
Thank you for measuring the depth, a job well done.
Yeah that rock in the middle is about half way up the Strid. The day i filmed this a young guy actually jumped to it. You can see him stood on it in one of the drone shots although my drone was fairly high at the time. I considered doing the same but i just didnt have thee confidence to do it lol
I can imagine over the centuries the locals taking outsiders who weren't very nice for a nice picnic swim on the river.
65 m deep for a river is absolutely insane. There are parts of the ocean several kilometers off the coast that are not that deep… 😨

"if you visit this place, please do it safely" as the drone flies over some dude standing on a rock in the middle of the Strid.
That's the depth that the sonar picked up from directly below. You could have been reading the depth of an underwater shelf or overhang at 60m but the bottom could be much further down than that.
It's a mind blowing thought.
Ive been to the strid many times...it amazes me how anyone could want to stand near the edge. There is a strange feeling looking into that murky water, knowing the sheer force running underneath.

I do believe this river is easily 30m deep but not 60......regardless, you have made an excellent video and i hope some of the mysteries of this place will be finally revealed.
I heard somewhere over 1000 people have died there 😵
It's been about forty years since I visited here. I remember swimming in the wider section and then walking up with the family to the falls section. I knew it was dangerous, but seeing your readings, just makes me think as to how powerful it is! I seem to recall seeing some names carved into the rock around the falls section of victims and there had only recently been a fatality (this would have been around 1982) so it was quite sobering, even for the eleven/twelve year old me. A beautiful part of the world but oh so deadly if you were careless. Thanks for bringing back some childhood memories.
My uncle Sid use to jump over the rocks with me in his arms over sixty yrs ago he was an athlete,but I wouldn,t recommend , it's a stunning places to visit.
ur parents should be fired for allowing u to go there.
But then again ur british , dont they start giving you vodka straight out the bottle around age 8 or 9?
I’ve been swimming there as well. I remember there was always talk of the people that recently died. As long as you’re careful and swim strongly, you will be ok.
Watching this from California! That is so incredibly scary deep. Awesome video. So glad you did not fall it, terrifying to be that close! Great video!
Wait a minute, if the source of sonar beam is not pointing straight down you will get false depth reading. If you hold the ball like you did, it will aim diagonally and resulting measurement will be off quite a lot. The correct way would be to let the device float freely in the current and take some path along the stream. Though turbulent water will still cause some deviation but you will get much more precise figures.
Quite aside from the fascination surrounding the Strid, I'd love to visit this part of the Yorkshire Dales, what a beautiful bit of country.
Cool video, thanks for making it!
I wonder if the turbulence is rotating the ball so it it measures slightly diagonally (away from vertical) or if the frothy bubbles do anything to the sound waves?…. Certainly staggering shape of a channel!! Thanks for giving this a go, wonder what other super deep river channels there are?
PW: I believe the air bubbles are affecting the readings.
The ball is gyroscopic and weighted, the sonar always points down.
Bolton Abbey was one of my go to places when I wanted the serenity of walking British history and getting tea. The tea shop nearby was one of the best.
Fountains Abbey was my absolute favorite.
1985-1990…loved every second living in England.
I think you went a bit close just to take a depth reading but such an interesting video, this kind of content wasn't available when I was doing research on the Strid earlier this year. You legend!
Omlg it will suck you in like a demon it will a hand will reach out and suck you down you will never recover you should really cover yourself in bubble wrap and chain yourself to the floor in your house its the only positive way to be safe oh yeah also make sure to cover yourself in hand sanitizer to avoid the super scary reset cervesa sickness because you might get pulled in the river and die from corina.
I mean he knows how how swim right? Even if he fell I'm sure he'd be fine just swimming back out. The danger comes when there's flooding and the river current is moving too quickly.
@@miked815 actually the problem is the water is so turbulent it becomes aerated and anything that falls in sinks to the bottom. Theres no swimming out of the strid!
Been waiting for someone to do this for YEARS!!! Legendary!!!!
Please be careful though. The strid is no joke (as you know) and you seemed to get fairly close the edges!
Great place many quality days spent here, surprised by some of your findings. Deadly water in parts my heart gos out to anyone who's lost a family member to this river. Stay safe if visiting 👍
Must have been some pretty wild conditions for a river carving through rock sideways to be the path of least resistance.
Probably a fault line creating a gap
It looks so harmless at that flow level. The Kern River (near Bakersfield, CA) has similar under-tows near the end of it's canyon. A real killer.
It's like beautiful sirens calling travelers into their doom.
I live in Bakersfield and the amount of out of towners that misjudge the kern and end up being fished out is crazy
The Kern River certainly claims a lot of lives.
@@toohighstrung do they still have the tally of deaths at the mouth of the canyon? It’s not called The Killer Kern for nothing.
@@crystaledwards9878 they do and it tragically goes up every summer..
all i could think about while watching is just how beautiful that area is, the greenery of the trees with the turbulent water in the background gorgeous!
Very interesting. Worried you're putting yourself at risk. Is it possible that the sonar ball is dragged to be at an angle from the point of suspension so maybe you're measuring a diagonal distance rather than vertical?
Yes but that wouldn't be anywhere near as sensational
It is weighted to specifically counter that problem. Irs likely only off by 10-15%
Absolute worst case at like 45* would only be off by like 30 or 40 percent. That would still leave like 40 fucking meters.
Depending on the rising air bubbles your sonar may not be getting accurate signals. Good videos, crazy to think that it's over 150 feet deep. Also crazy to think that that ledge you are standing on has about 10 feet of rock and underneath is near 200 feet of water.. would be cool to test how far under those ledges is void till it hits am actual bank wall :)
Yeah my thoughts exactly - the speed of sound in aerated water is likely to be much lower and give erroneously high depth readings. It didn't seem like he calibrated with a reference depth in the turbulent water or anything? Not the best science process but still a fun video I guess.
Im no expert, but i was also thinking that the bubbles could be giving a false reading.
I gave a like, which is getting rare these days because of the amount of content good vs bad..
But that the author asked in a genuine way and explained why.
Then off course such a small gesture will be granted. Absolutely.
That it's a interesting video about something that scary, is just a lovely treat
Really interesting video, my girlfriend’s folk live at Bolton Abbey, I can’t wait to tell them! We knew it was deep, but nearly 70m! Wow. They say the ‘Strid’ gobbles you up, but you may never surface! Think you proved exactly why that’s the case! Great video! You Sir, have my subscription!
Ayyyy that's awesome man love to see a local in the comments!
Christ, just watching a few of your other videos! The branches, ledges and undercurrents you filmed at around 30m made my skin crawl! I honestly got goose bumps! I think it might be that you can kind of image you could swim (float) down the length of it. It seems so innocuous. Then the reality of the thought kicks you in the behind! If you went in (not to labour the point) but I think it would be like an underwater maze of ledges and you’d never find the surface again! Enough of that now though. But great series of films, thanks for posting!
This is great! It's pretty amazing that no other research has been done on the area. Blessings to you
Thank you! You too!
Great infotainment, the YT Algorithms gave me a treat if a video
Much respect to you from Ghana 👍🏾🇬🇭 West Africa.
Never heard of this place before, but I can certainly see it's really dangerous and deep. No wonder people get caught in that current and get bashed to death. Be safe. US 🇺🇸 California.
I'm thinking that the ball the sonar is on is getting tilted by the force of the water. This means you're likely reading the depth at an angle.
It is still insanely deep, but I don't trust the accuracy.
Quite cool. Thanks for the effort you put into this!
As a fisherman that uses portable fish finders, that's exactly what was happening.
On the two models of Deepers that I've seen, the actual transducer is gyroscopically mounted inside the casing, with ballast. So no matter the orientation of the outer case, pings are directed straight down.
@@QuantumLeap83 All of the information I've read and researched says different. If you have photo's of the internals with gyroscope mount/chip or link showing either one I would be interested. I looked at buying one but didn't because they didn't have a gyroscope in them. No flame just genuinely interested in finding out.
@@1radarghost That sounds like a glaring design flaw, that it would have to be deployed with such precision or it returns inaccurate readings.
This reminds me of about a year ago we were visiting the Kootenays in British Columbia going on a hike, and we were walking along this little stream, just about wide enough to step over.
We saw some ducks on the other side, so my dad picked up my little sister (7) and went to bring her across, but he fell in and it was suprisingly over 6 feet deep with a crazy strong current!
Unfortunately there was a death
My dad's phone was absolutely soaked and i think it broke
And i thought that was deep!!
Crazy how deep these little cracks or rivers are
I lived in a 21-story high-rise dormitory for college and I just googled the height of it and it's shorter than the strid is deep according to your readings
Nope. Nope. Nope. This place is so beautiful, and that 'little stream' is so damn terrifying.
Good to see ya pop up on my feed again! I've seen people talking about this project since you posted!!
Thank you for the experiment! I search this information everywhere, glad some one test it and share! Really amazing! Good video! I will sub to your channel! Be careful! Hugs from Brazil!
Just seen the end of your message brilliant to see Brazil viewer 😀 love seeing different countries on the videos hope all is good in Brazil man! 👍🏻
To put this into perspective, the UK's tallest roller coaster "The big one" is 65 meters tall. That's kinda scary deep. en.wikipedia.org/wiki/The_Big_One_(roller_coaster)
Never head of this beautiful British river or the strid ……amazing video ❤
It’s eye opening video, thanks for sharing:)
Glad you enjoyed it!
Definitely deserve a follow and like for the big risks involved❤️
Thanks man good to see you here!
I miss running up by Bolton Abbey when I was stationed at RAF Menwith Hill in Harrogate.
I've dived the River Etive in Scotland which is very deep and narrow in sections. It goes fro 2-3m down to 15m. The current in the deep sections isn't bad as the flow isn't as constricted. Still an exiting drift dive with lots of overhangs and caves. In the shallower sections it's a bit like a washing machine ;-)
Sounds pretty dangerous to me. What did you do to guarantee the safety? And was it cool?
Great video. All the others focus on the tragedies - this one has a charming pastoral sensibility. Just nature being nature - and your adorable sense of discovery. Love it.
I love watching people follow their passion... I personally have no interest in this whatsoever, but your passion kept me watching. thumbs up!
Roughly 216 feet deep. Really deceiving and creepy at the same time. Could call it the devils deception to death.
Fascinating! greetings from New Jersey, USA.
how could i click away from such a captivating subject buddy? hackin on ya. thanks for the video.
He's basically standing on top of a 21 story building. Think about that, take all the time you need.
Jaw dropping, that is a great perspective, 21 stories.
I saw an article that claimed the Strid was only 30' deep. Apparently some scuba divers had been in it before it was closed to diving in the '70s. One way to check this out is to measure the flow of the River Wharfe and calculate what volume the Strid would need to be to handle all that water passing through it. We know how wide the Strid is, so it should be easy enough to determine its necessary depth.
This assumes you know the speed the water is travelling which we just dont. you could measure surface speeds but even then things like turbulence makes it difficult
The way water forces through there it may have been a correct reading in the 70's and this one may be correct now. It's shocking how many tons water can shift.
It doesn't appear to be anything approximating a rectangular section down there - there seem to be a lot of caves and holes so even knowing the volume may not get you the right depth, which is insane
@@tricky1992000 There is absolutely no way ~180' of rock was eroded in 50 years. No way. Water erosion on that scale would take hundreds of thousands or millions of years.
I wasn't referring to erosion of hard rock but shifting of materials, just one major flood can change the depth of water in a spot @@cptawesome11
Loved this video mate, really interesting. Well done
Cheers Ben good to see you here mate. Enjoyed your fell walk in the dark video really good idea that one. Hard to get the lighting right for viewers but you done a good job with the photography was awesome to see
@@jackasnacks Thanks a lot man. Really appreciate that 😊 Will definitely be sticking around to see what you’ve got in store next!
I wonder how accurate that is. I’m surprised more research hasn’t been done. Good Drone Adventure.
Curiosity is enough so i am going back with another test this week. Going to try and get some under water footage this time so if you're interested be sure to look out for the next upload! Thanks for the comment though love the strid community
I've always had a fascination with the Strid. As far as I know, there isn't any footage from under the surface, so you would be a first. Not sure how easy it would be, but setting up a cross frame across the Strid to allow a GoPro to be dropped by a boom on a 10 meter pole might show a decent view of the rock undercutting
@@andrewpepiot1855 need a lot of light
Even though I was listening to Editor Jack I was still really concerned about you slipping. What a terrific place.
As you mentioned that the bank is actually an overhang with cave systems underneath, could it be you're measuring the walls of cavities hollowed out by the turbulence? I can imagine that the sonar ball is not always 'looking' straight down.
Nevertheless, amazing sizes in relation to the width of the Strid! Nice video. I 'Thumbed up'
that edge your walking along is basically like the grand canyon, but filled with water, and narrow ofc.
That's amazing thanks Jack! We've got the devil's bridge in Wales, I wonder how deep it is there, looks very similar
There is a Devils Bridge too at Kirby Lonsdale which is very deep too..
Wow, just happened across this video. It's amazing that a narrow stream that looks as though you could wade across it could be so deep. Incredible!
As Bolton Abbey ruins are a favourite day out and school trip destination a walk to the strid tends to be part of the day. Im amazed there arent more deaths.
To put this in perspective for people who have played minecraft: the ravines in that game are about 40 meters deep. This is more than one and a half times that. In fact, the normal water surface level in the game is 62, so this is about as deep as a drop all the way from the surface to Y=0.
@@asbestosfibers1325 A ruler does not convey the kind of distances we're talking about here. And I've used metric my whole life.
@@Nyerguds neither does a virtual space fool.
Go play in reality some.
@@asbestosfibers1325 Not sure about you, but I don't have many convenient 60-meter ravines around my neighborhood to compare with.
@Nyerguds I don't live in minecraft land.
Pretty fucking sad if you do.
My references are to the real world because that's where I live.
I welcome you
Absolutely amazing!!! Thank you for sharing. I live In Massachusetts USA and we have gorges here. I believe it’s one in the same.
Great video, thanks for introducing me to the Strid. I was skeptical of the 100% fatality rate, but 65+ meters deep?! That's 195 feet! On a river maybe 10-15 feet wide? Incredible.
That particular section is only about 4-5ft across due to the way the rocks cover the majority of the top, that’s why it’s so scary, people often want to jump across, but one slip.. you can be pulled down due to the undercurrent, quickly end up under those rocks and get smashed about in the area below 😕
Does a sonar depth meter give reliable results in frothy water filled with air bubbles?
Good question… and I suspect not. Sound moves slower through air than water, so lots of bubbles might present an errantly deeper reading.
Mate that was amazing!!! From Portland Oregon, USA
Do people fish there?
People do fish here yeah! Whilst i have been here i see many people with fishing poles stop by for an hour and try their luck!
Its about £60 for a day ticket and only 6 a day get handed out river season in Bolton Abbey.
Crazy. I've sat on the edge there with my feet in the water, I had absolutely no idea. Great vid mate, really interesting.
I’ve recently heard about this place and is fascinating and scary. Cool to see someone investigate it . Cool video. I wonder if at one time it was around 30 m deep but since the water is funneled and moving so fast there,that it erodes the rock much faster?
Yes, that's partially the case. It is highly probable than the rock in the walls of the river endures more against the erosive force of the water, so it gets deeper instead of wider
I never heard of it,looks lovely,the surrounding area.
Good job, clearly worth the initial investment on your end
Hello from Kansas City, Missouri, USA. Absolutely terrifying stretch of river. I'm so glad you made the video without being harmed. In the States, people are so litigation conscious that a dangerous stretch of water like that would be cordoned off and covered in Danger signs.
Hello from Kansas City, Kansas!
I love your city. Some of the nicest people I've ever met. 💕
The worst part of England is people trying to own and section off the country. Yorkshire is my county and I'll go where I bloody well like 😂.
Well done, sir! Thank you for doing something no one has done. That is crazy deep. PLEASE, don't get closer. I was stressed watching you try to get the depth at the 65m mark. I would need a rope tied on to go to that point.
In the past, I've stepped into a pair of Simms and fly fished in N. GA a lot... but I'll never look at another trout stream in quite the same way anymore !!
My great great grandfather is supposed to have jumped it regularly as a short cut to school. Insane when you see it up close.
I feel a great disturbance in the Force, as if millions of professional marine geophysicists cried out in agony…
Looking at the numbers and the channel conditions (esp the bubbles & turbulence), I think you’re getting a few erroneous measurements. Probably better off with a mock-up leadline? Need 50m of rope, a very heavy weight, a tape measure and patience to tie a load of knots at 1m intervals ;) Great to see someone interested in investigating the depths though. Fascinating world, underwater.
I had exactly the same thoughts, turbulence and air bubbles affecting the sonar readings.
@@Swaggerlot but the readings are not turbulent. If that had an effect, wouldn't the readings fluctuate?
@@ThorRuneHansen Quite possibly, but I do know is that things such as that do cause issues with sonar signals.
@@ThorRuneHansen I would imagine there's a pretty consistent aeration of the water in the turbulent areas, so it seems like a steady, but probably wildly inaccurate measurement is likely.
Just saw this after I posted a comment, air entrained in the water would throw off the readings a lot. The speed of sound in air is a lot lower than it is in water and could give readings showing a greater depth than there actually is.
I need to see this place, im only 20 miles away at the most. Good video fella 👍
