Thanks Bob! You know Snow White? Sorry, horrible joke you probably heard a million times. I just couldn't resist. Have a great week. Hope to see and update of the over topping. Thanks again.
Thanks for the great coverage. Its different watching an area that is my familiar backyard, definitely impinges seeing all the places dear to my heart. Then at the end to see the Hope Slide and memories of driving through that eerie land a couple of days after the first 'road' was punched through for local traffic. This province is nothing if not spectacular and demanding of respect.
Yes I was there shortly after the Hope Slide cat trail was pushed through as well. One thing I clearly remember is how much the slide had sloshed up the opposite mountain wiping all the forest and soils off it to bare rock, a few hundred feet above the valley floor, and then sloshed down the valley like a bath tub when someone dives in.
One of the First Nations did a fly over not just of the slide but also of the areas impacted. The slide looks so much bigger than I envisioned! It's good to hear that the downstream impact of a breach is less than you expected. Others in the comments are saying that the dam was over topped a bit ago. That's also good -- thinking about not just a prolonged back up but also looking forward to fall/winter rains which could add significantly to the impacted areas.
Update: The water has found a way through, not overtopping but from the one chopper footage I’ve seen it appears to be internal piping and erosion that’s burst through midway up the downstream slope. This means that the entire mass of rock and earth is filling with water like a sponge, literally the temporary dam is getting soggier and soggier and thence more unstable, which could lead to a more catastrophic failure where the dam just slumps forward and the water flows out.
Thanks again for update … clear, concise, and in language the average person can understand. Glad that you referenced the Hope slide … Also glad you pointed out that this could take an extended period of time to resolve, and that currently still activity in slide area. Imo will be hard to keep people out of dry river bed downstream. So enticing to a certain segment of population. 😮
@@GeologyHub and as far as I know one the bigest examples of landslide-made lakes is located in Tajikistan. The lake is known as Sarez Lake, it is 500 m deep and has a volume of approx. 17 km3!
Thank you for the coverage of this. All of the other "geologists" I follow here on RUclips have said nothing about this. I guess if it isn't rocks or volcanos they don't seem to care.
Much of the coming scenario depends on the make-up of the slide material. If it is all sand and mud and other fine material, the breakthrough can be very fast and possibly catastrophic. If the slide contains a large amount of coarse rock (as did all of the the Hope Slide that you draw on for a false comparison for exactly that reason) it will considerably slow down and ameliorate the speed end energy of the new channel erosion through the slide. Maybe a better comparison is the 2010 Capricorn/Meager Creek/Lillooet River slide north of Pemberton that contained a mixture of (glacial) sediment and rock material. In any case, the consequences for the upcoming sockeye salmon migration will be devastating.

Thanks for all your work, and especially for providing us a space that is based on data 🙂 Btw - The Fraser ("fray-zer" rather than "fray-zier") River watershed had another significant slide in June 2019 along the Fraser River north of Lillooet near Big Bar. This was also when Chinook and Sockeye salmon were migrating, which are endangered runs. A lot of effort was put into attempts to move the salmon upstream of the slide, and yet there are still and will continue to be ramifications on their populations.
A day ago I found a great vid here on YT of a Fly over the Chilcotin River landslide, made by the local indigenous people. It is a great help in understanding the size of the slip. Commenters below say newer video from the same source shows that some flow downstream has already begun.
CBC Vancouver posted an update on this platform at approximately 16:30 today (August 5). They note that for now, the release is gradual, however that could change. I'm glad they also mentioned the potential for further slides above and below the slide. I know you and others trained in earth sciences would recognize this region has a history of landslide from the number of scarps and scars along the rivers. Thankfully it has been dry for the last bit and forecast to stay that way in the near future, so discharge is moderate and the build up of water not as great as it could be.
Thank you for the great content. I appreciate your reporting on this event as being valuable to this slow Schmo reader because of the following characteristics: Firstly, the balance the series achieves between being timely, accurate, and informative yet succinct. This keeps the geo-tech concepts fresh and simple for the average viewer. Secondly, your well-crafted reports are elegant, easy to grasp, and edifying - without being terrifying.
I remember the Hope Slide! My father took me up there 2 days after it happened, before the RCAF plane crashed into it. The mountain was still making threatening noises, and the temporary road across it was one lane of rough track, but they were working on it. We couldn't see the whole side of the mountain because of low clouds, and it was snowing. Perfect conditions for flying into a mountain!
It’s weird to see those two center point pivot irrigation systems along the river bank. PS - appreciate your video and information about this incident. Glad it’s not worse case. PS2 - reminds me of the 2014 Oso landslide in Washington state, that killed 43 people, destroyed numerous houses and destroyed part of a state road.
Could you explain someday about the landslide in Norway?,farmer dug a foundation for a barn and placed the dirt at waters edge,and the top layer of soil some how washed away three farms into the water,it really was a Helluva thing to see,considering it all started with a foundation for a barn.
There is an extensive video on this if you search. Quite detailed on how the salt concentration in the clay keeps it more or less solid. Introduce too much water or agitate it and it turns into a liquid. Which is what happened there
By the looks of the amount of water cutting through the blockage ( started at 9:00 am ) it won't take too long to drain the backup. Last picture i've seen was at 11:30. It's coming fast and furious.
Keep it coming brother! I prefer your narration and objectivity to anyone else. There is no close second. Maybe if Ryan Hall suddenly became an expert reporter of geology. I hold you two in equal regard, expert reporters of the most accurate information and trustworthy commentators when introducing personal viewpoints/your own educated and dedicated opinions. That is amongst the highest compliment I have available to RUclips content creators, and hat’s off to you, good sir! Keep being excellent!
@TSUNAMICali yes it would be the end Of Squamish but Mt Meger and Mt Caylay could end Squamish too. Squamish is the Naples of Canada. Whistler would probably be gone too. But if Mt Garibaldi erupts into the Pitt river valley with enough force it would instantly melt every glacier feeding that river and send it straight to Vancouver. A VEI 5 doing a Mt Saint Helen and laterally blasting to the east could send Pyroclastic flows 20 kms away. Check the snowfall/glaciers footprint within a 20 km distance to Mt Garibaldi (look to the east not the west, look into the Pitt river valley)
Slight correction, the worst case scenario that THEY believe is most likely. Remember that even expert opinions are still opinions and even they can get things wrong.
I would suggest a high chance of a lahar developing, as the water flows and picks up mud and debris the rate of erosion increases and the flow increases. This can increase at an exponential rate. What flows downstream is not a water flood, but a mud flow that erodes more debris as it goes. The fallen timber in the mud flow will most likely take out many bridges downstream
I live here and as a recreational fisherman this is a real bad scenario for the millions of salmon beginning to make their way up the Fraser River from now until late October and the steelhead after that
From a video uploaded about an hour ago, it looks like water is just now beginning to flow over the top of the landslide. I guess now what remains to be seen is how long it will actually take before the landslide gives out.
@@kyleslater5245 Yeah, that's pretty much what I meant. Pressure probably won't be building anymore with it overtopping, so it's a matter of waiting now, and as he said, that will probably be a while.
It will liquefy with that whole lake behind it. Check out flash flood footage for a mini example of what this would do. It's mind blowing even on that small scale
It will turn into something similar to a lahar (a volcanic mudflow). Nothing will stop it until it loses energy. By then not much will be left (debris wise) to create a natural dam that will cause much of a problem.
Its broken through and has eroded a bigger and deeper path so the water is dropping quite Rapidly. EmergencyInfoBC has an upstream and down stream cam which updates every 15 minutes.
Nature has it already controlled as the water breached and slowly drained the river a bit. It's getting eroded quickly but the downpour isn't that severe as expected, according to recent flyby videos. There's no way for human intervention to slow down the erosion since the grounds are unstable for any transportation. The best they can do is to prep for evacuation in advance and let nature do its thing.
I disagree with your statement that it is not safe to kayak in the Frasier River in Vancouver. The estimates are that any flood from a worst-case scenario breakthrough of the landslide would take 12 to 24 hours to reach Hope, 60 miles upstream from Vancouver. When a breakthrough occurs, there will be plenty of time for the Fraiser River to be cleared in the Vancouver area before the 30cm/1 foot flood gets to Vancouver.
Currently 6 hrs since this video came out, and it has breached the top, and is currently breached the dam. This was scary thinking it could whipe out major highways, It wont be that bad though as it is a slow release to start. Everything will be fine. Its really not as bad as it was hyped up to be.
What the engineers must do is create a narrow pathway across the areas of least resistance, over the slump. Allow water to slowly run thru this channel. This will allow the water to flow and create a widening, slow flow that over time it will relieve the back water without being fast and catastrophic.
The Fraser River (not Frazier), especially closer to Vancouver, is a working river, meaning; tug boats, log booms, barges, free-floating or stuck logs some of them huge, and all the river banks along both sides are either docks for industries or log booms. The tidal effects are plus/minus three metres or more. At low tide the shallows reveal barnacle-encrusted metal and giant log roots. Believe me NOBODY is pleasure boating on the Fraser River, especially not when there are so many better places nearby.
we might be alright, i guess the sheer size of the landslide is protecting against a runaway erosion event, for now. lets hope for more of this gradual release. theres a sweet spot of waterflow where it goes fast enough to begin draining the "lake" without moving fast enough to erode the whole dam, and thats what im hopng for. what we dont want is the overtop being insufficient to actually drain the dam, if the water is still rising despite the overtop, well i cant predict what would happen.
Looking at the current footage it looks as if, so far, that it’ll be a slow release as I guessed earlier. The problem with this slide dam is its width - if it were only 50m wide there could be a catastrophic release, however it’s several hundred metres wide so that’d be unlikely.
Another famous Canadian landslide would be the Frank Slide, where with no notice, Turtle Mountain obliterated part of the town of Frank 4:10 AM on April 29th, 1903.
It's always strange for me when you do a video about some geologic feature or activity in BC. Normally our beautiful province pretends to be some other place when it's featured on screen.
When you put it in centimeters or millimeters it doesn’t sound bad at all. It sounds like a creek swelling. Maybe your feet will get wet for the maximum fear you’re trying to generate add the actual feet and then you’ll see the fear will go away because it’s not that deep .. But for you to get more clicks, you have to keep it as sensational as you possibly can so maybe you should couch the terms in cubits
There are too many variables to make a viable prediction. The worse case scenario(s) are based on a catastrophic breach creating a pulse of water. A slow erosion will elongate the pulse causing much lower peaks.
A siphon only needing rigid walls for the upstream to lower section where flow is assured could help keeping the fish from having fowled water, Maybe add in endangering youtubers that don't own drones wanting to get close for videos. I'm sure there is a few web searches for campsites high next to the river.
I've been watching Dan Hurd for some time. When he's out panning by the Fraser you can literally see evidence of fresh rockfalls all over the place. Big old jagged boulders with no algae on them just sitting there.
Blasting a small trench into the blockage to help the river flow over it, might help prevent a sudden and highly destructive collapse of the naturally formed dam. Depending on the stability of the land that collapsed into the river. My theory is that allowing it to flow over the top slowly will allow for a gradual erosion to cut through and slowly drain th excess water built up behind the blockage. Although that theory could also prove to be false.
it overtopped today. I have to wonder if it's possible to get equipment up there and dredge out the channel to restore flow before the dam breaks naturally
So, what about the people upstream who are affected by the rising water levels of this slide ? There is property upstream being flooding already but all the news covers is the "potential" downstream flooding.
Heard its overtopped already, but I've been very disappointed in how much video has been shared online. Seems like everything I've seen is 8-10 hours old already. I didn't see a video of it overtopping until just about 30 minutes ago and the overflow started 8 hours ago.
I guess pumping water from the lake to below the dam is out of the question...digging channels to lower the max level of the lake building up. Can you dam the water flow up stream ? slow it down ? what is flow of water upstream, what is area of lake and contour of land, easy to calc at what rate water will rise and what rate you need to exceed to lower the lake level by pumping down stream.
The river has now overtopped the landslide/dam. It's flowing quite slowly so far.
Wow, from 48 hours to 365 days to 10 minutes.
look for the video titled:
"Water is now flowing over the top of the Chilcotin landslide August/05/2024"
any links anywhere showing this, i think utube is surpressing it

A siphon only needing rigid walls for the upstream to lower section where flow is assured could help keeping the fish from having fowled water, Maybe add in endangering youtubers that don't own drones wanting to get close for videos. I'm sure there is a few web searches for campsites high next to the river.
Reminds me of the Oso, Washington landslide that also blocked a river.
Time will tell. The End.
I've been watching Dan Hurd for some time. When he's out panning by the Fraser you can literally see evidence of fresh rockfalls all over the place. Big old jagged boulders with no algae on them just sitting there.
Blasting a small trench into the blockage to help the river flow over it, might help prevent a sudden and highly destructive collapse of the naturally formed dam. Depending on the stability of the land that collapsed into the river.
My theory is that allowing it to flow over the top slowly will allow for a gradual erosion to cut through and slowly drain th excess water built up behind the blockage. Although that theory could also prove to be false.
It has overtopped the slide as of 2 hours ago and is beginning to flow again
it overtopped today. I have to wonder if it's possible to get equipment up there and dredge out the channel to restore flow before the dam breaks naturally
So, what about the people upstream who are affected by the rising water levels of this slide ? There is property upstream being flooding already but all the news covers is the "potential" downstream flooding.
Wouldn't the Hebgen Lake slide be a good analogy. It's 65 years old now.
It has breached that earthen dam and created a new channel resulting in flooding.
The landslide broke about half an hour ago, roughly noon, 2024 08 05. Prayers for everyone downstream.
Interesting
But if it drains fast it might trigger new landslides upstream, its an effect caused by oversaturation of the hillsides!
we just need a large, autonomous ditch-digging machine
get your kayaks ready ✊️
Lol, it looks a bit too rough for that :D Barrel?
Imagine what will take place after the 9.something cascadia quake happens this will take place in multiple locations
I'll jump in my Indian Arms Deep Cove sea plane and head for Kelowna. Drink wine, eat cheese.
Heard its overtopped already, but I've been very disappointed in how much video has been shared online. Seems like everything I've seen is 8-10 hours old already. I didn't see a video of it overtopping until just about 30 minutes ago and the overflow started 8 hours ago.
Try TheBirdNerd. He just released one of it fully breeched 10 minutes ago.

Given the fact that the government is incompetent, I trust you more
Given the fact that there will be a provincial election in October, one would expect comments like that. But this is not politics.
Have you been watching the Trudeau government?,it's like Cheap Fakes with the American msm.@@stevejohnson3357
@stevejohnson3357 has nothing to do with politics. Just a truthful statement of facts.
@@stevejohnson3357Government is the Peter Principal in full force.
the natural dam has started to seep meaning that it has started to breach
I guess pumping water from the lake to below the dam is out of the question...digging channels to lower the max level of the lake building up. Can you dam the water flow up stream ? slow it down ? what is flow of water upstream, what is area of lake and contour of land, easy to calc at what rate water will rise and what rate you need to exceed to lower the lake level by pumping down stream.
Too late. It's already gone.
I thought you were going to compare it to the frank slide but i guess those numbers are less exact
