The more I learn about Iceland, the more I want to visit it! What an incredibly fascinating place! Thank you!
Me too!
I was there this past May for a few days. It is fascinating and I could have spent a lot more time exploring.
When I was stationed at Naval Air Station (NAS) Keflavik in 1979-80, went all over the countryside. Wish we had a visiting professor to explain all these landforms to us! There is never a lack of geologic surprises all over Iceland!
Wow! Fascinating stuff, thankyou Shawn 🦄
Oh, wow, you went there. I have been following your news videos about the eruption. I look forward to more information from you as you explore.
I've never missed my homeland so much until I came upon your channel Shawn. Thank you for sharing, hope you are having a wonderful holiday season. 🕊️☯️
How interesting - kudos to good balance! Thanks for the adventure!
I love this stuff, thank you! One suggestion for the future, though, would be to pan the camera more slowly. The feeling's a bit vertiginous when the landscape is whizzing past. Anyway, I love hearing your insights into these landforms, cheers!
Thank you for the fields series
That is fantastic!! Thank you!!
Thanks for the video and explanations. Previously in another video, you mentioned "your website" and additional information. I cannot find your personal website. Please advise..
.
Wow my son's grandmother went to Iceland a few years ago her daughter does 4 x 4 tours she said there was a big crack in the ground you could walk through wonder if this is it. Iceland looks such an interesting place
Thx Prof for another excellent geo-ed adventure vid. ✌🏻
Happy New Year everyone.
Water and lava produce a variety of features. Thanks Shawn.
Cool feature! Thanks, Shawn!
Very fascinating place.
Looks like caution is needed walking / hiking there as it isn’t even but all looks the same. Beautiful scenery!
So incredibly cool to see the plate tectonics in action.
Thanks again Shawn ! Every time I watch yer videos I learn something new. I live in northern Cali at the southern extreme of the Klamath mtns and have been fascinated by my surroundings. Retired I now have time to study geology and most of the rock here is metamorphic and I’m continued to be awe struck with Gods great power ! Thanks again
IIRC: Moss is often one of the first organisms to colonize exposed rocks and new land. They help to provide habitats for other organisms and places to which other sedentary organisms can attach themselves. They aid in extremely slowly breaking down the rocks and extracting the nutrients and minerals life needs and the surface of the moss aids in the capture of eroded material and dust from wind and water. So moss helps establish the formation of the soil by creating a sort of nucleation site for other life to grow.
There is an amazing book called 'Gathering Moss' by Robin Wall Kimmerer. It is an excellent and quick read and doesn't require any background in biology, botany, or science. It gives an awesome overview of an organism we often overlook in a fun and exciting manner while also weaving in some great prose on nature, life, and living and the stories that come with it.
Sphagnum moss was used as a wound dressing in World War 1 because of its absorbency and anti-bacterial sterility.
Very lovely photography. Interesting.
Thanks for sharing this beautiful and stunning walk. The "evolution" of this area is amazingly awesome. I really enjoy your citation and explanation of the various videos you have produced. Very interesting and many thanks.
Great info! Best on the tube. Look forward to more. Should do some geology vids on the areas you climb and some climbing. Look forward to more. Thanks.
It seems an alien world, totally amazing. You have a better head for heights than I do. Thanks for the unique visit.
❤ learning more about geology. I so appreciate your videos because I can’t afford to take any classes due to the expenses and because I’ve gone through five spinal surgeries in the last three years, so mobility is a big problem for me. Thank you so much for sharing your passion, knowledge, experience, and education in this amazing field of geology. Your videos really make a big difference in my life and spark and wonder about this amazing earth.
So beautiful, thanks for geology info so interesting...wow ypu are IN iceland!!😮❤
Best in all
2024 everyone🎉
Thanks again Shawn for an interesting walk! Cheers from Minnesota
Impressive. Thank-you.
Amazing! Thank you ❤
Great place to show us. It invites exploration! [Once in a while, might you come in closer to the flora? (Personal interest...😉) ] Love the explanation about brecciation, and the orientation of the fissure to plate boundary. Beautiful and really interesting. Thank you!
Thank you.
Fascinating 😊
Thanks!
Love your work, Shawn. A suggestion: don't move the camera so much--it's hard to see anything when the camera moves. Otherwise excellent presentation and opportunity for the rest of us to see an extraordinary place. Thanks.
Yes, fast closeup panning is not productive. You can’t tell what you’re looking at. The rest is most excellent and informative. Keep up the good work, we’re all loving it!
Nice slot, always a good experience to be immersed in the heart {muscles?} of the Earth. I'm intrigued by the "cleanliness",of the break, the torsional shearing forces that spread the crevice-
I always enjoy following along on Google Earth.
Wow. Reminds me of the Paths of The Dead. The path Aragorn, Gimli and Legolas took to the Army of the Dead in LOTR... 😁
I thought the same thing!
This is my first view of a non-wintery Iceland. I would enjoy walking over these mossy mounds.
Has anybody ever tried to take a core sample from the bottom of the fissure? It looks like it goes down much deeper and has been filled in with debris and soil over time, so taking a core from the base down until hitting solid rock could give a more accurate idea of how old it is and whether it was a gradual formation from slow spreading or a single more violent tectonic event.
I pucker every time you point that camera down from the top of that fissure. Oy,
Reminds me of "Earthquake Fault" along the northern flank of Mammoth Mtn -- which isn't a fault at all, it's a fissure like Lambafellsgjá, pulled apart by tectonic forces but not as a fault - just pulled straight apart without any lateral or vertical faulting.
No palagonite, oh no! Thanks to your channel, "Palag'night" is what my wife and I say to each other at bedtime.
Treacherous landscape to walk in.
7:40 Careful, Shawn!!
Ur awesome bro🤙 that's an great feature it rele is! U bring the drone man? Either way the cliftop shots are fantastic! 😍
Perhaps there are lava and ice interactions that are unique from lava and water interactions
good grief! I didn't expect this video to bring on screaming vertigo! 😂
Very interesting, is there any wildlife in that area?
Now I see why they filmed Star Trek in Iceland it's like being on another planet and another time 😎
My fear of heights as I age gets so much worse made confirmed by watching this video 😬😁 Gorgeous landscapes though.
Hi Shawn, There seems to be such a huge difference between the response of the Icelandic people vs American people in their reaction to the impending eruption. People know an eruption is coming soon, but have little to no hesitation of soaking at the blue lagoon. They just want to install a siren. Is the difference from the common nature of vulcanology in Iceland?
*QUESTION* : Is this analogous to crevasses in a glacier? Thanks Shawn. 🙂👍
You weren´t wrong. It is about 20 miles from central Reykjavík yes. It´s just from the town of Hafnarfjörður(southernmost town/municipality of the capital area) that it is about 15 miles. But most tourists would just call Hafnarfjörður: Reykjavík, sure. I´m not too sure the "Hafnfjorders" would take a liking to that ;)
So this is the moss that burns when lava contacts it..I always wondered about that.
Professor, is this structure similar to the fissure in the East African Rift in south western Kenya?
There was a large pillow on the right as you were moving through.Check at 2:58 ish.
And, more visible at 3:04. Is it a pillow?
Why would it break so cleanly along a relatively straight line vertically and horizontally?
It must be very difficult to yank a rock mass into two halves by pulling on it from two directions.
Earth has lots of power when she wants to use it
Shawn
Be careful, Icelanders are quite protective about their moss and lichens! 😮
I kind of doubt that the rock in the fissure would be sound enough for climbing. Breccias, like the rhyolite breccias of Pinnacles National Monument (oops! National PARK! Showing my age here. It WAS a Monument 50 years ago when I first worked there!) The rock was described as presenting a lot of “portable holds” that you could take with you as you left the route.
Please explain to your viewers that is is highly frounded upon to walk on the soft moss.
Just like you dont want to walk on the crypto soul in the southwest
You should stick to the path and not hike on the moss to the top
The moss is quite fragile and you can destroy it and start erosion to start.
I suggest that you invest in a drone if you find the need to get shots like this and allow the vegetation to be in peace.
Please don't walk on the delicate moss! It dies when you step on it.
You really shouldn't be walking on the moss - or by your 'example' effectively suggesting to others its ok to do so
