The bizarre lava trees of Craters of the Moon National Monument in southern Idaho
Ғылым және технология
Learn about lava trees and what these strange landforms tell us about past volcanic eruptions and the ancient landscape that existed at Craters of the Moon National Monument. Geology professor Shawn Willsey takes you on an up close tour of these interesting features near the Wilderness Trail, a less visited area of the monument.
You can learn more about southern Idaho geology by purchasing Geology Underfoot in Southern Idaho and Roadside Geology of Idaho. Both available locally or on Amazon.

The impression of the bark gets very distinct when the flow results in obsidian.
Lava tunnels, lava vents ,lava caves, lava flows, lava bombs but I'd never heard of lava trees.....awesome.

So many terms.
So interesting...at first, before I saw there were so many, I would have thought they might be fumerols.
lava trees.. makes sense and a good name for it. Thanks Shawn.

Some geology names are simple and easy. Others not so much.
Incredible! I am so jealous of where you live in such proximity to amazing geology! Thank you again and again for sharing!

You bet.
Thanks for these videos. I really love geology and your videos help me to understand some of the geological features that are around the west.
Thank you for your time and information. I live not too far from Crater's of the moon.
I love your videos! Thanks very much!
fantastic....thanks
Excellent and very interesting piece. I'll have to travel back to Craters of the Moon and have a deeper look, the one time I visited there, maybe 12 years ago give or take, I didn't have much time to do more than a typical tourist trip to a major park -- a couple hours. The American west, even the north west, has great splendor with Yellowstone NP right at the corner of Idaho, Wyoming and Montana. The pattern with almost concentric rings of lava wrapped around the missing remains of a tree is astounding, I can almost picture the lava pilling up in exactly that way -- fascinating that the tree was reduced to carbon as it was pyrolyzed.
Another great video! A cool hike we’ve done is the Wapi Kai Puka where there are some really old and tall Rocky Mountain Juniper trees that have been protected from fire. It’s a four mile hike on pretty rough young flows. Pillar Butte is also worth the walk.

Thanks for watching. Yes, those are very cool places. I've been out to Wapi Park and hiked to Pillar Butte and it is very awesome. I didn't know about the trees so thanks for sharing that tidbit. Look for more videos from Craters of the Moon over the next few weeks.
You're making where we live so much more interesting! When was the most recent eruption in the Snake River plain? Thank you!

Thanks for watching these! I've got more from Craters of the Moon coming over the next few weeks. The most recent eruption was about 2,000 years ago - the Blue Dragon lava flow (featured in an upcoming video) at Craters of the Moon. This area WILL erupt again, maybe even in our lifetimes. When it does, it will be an awesome show!

@@shawnwillsey Interesting, because of your videos we went to Craters of the Moon this winter and rode our bicycles all around, we were able to find a few of these holes where the trees were! Without you videos, I would have walked right past them. Thanks again!

@@randallgd You bet. So stoked you were able to do this. The lava trees are a cool story.
Pretty nifty. Thanks Shawn!
I always called them tree molds. Very common in Hawaii.

The impression of the bark and the hollowed area where the tree once lived is called a tree mold. The piled-up lava around the base is called a lava tree.
Thx.
Interesting feature!
Thank You
Fascinating
Top notch!
Very neato, Shawn. If your brother is a botanist or arborist, ask him how old those little fir? trees are - in that dry land and cinder soil they probably take some good time to achieve even those sizes.

I only have a sister, sorry. But these trees are limber pines. Hardy plants.

These pines will be a lot older than you would expect in desert country like that. Limber pines are interesting and fun because of how flexible the branches are. We don't have those here in Washington. I saw them when I traveled and lived in the Rockies. I have forgotten nearly all the tree science I learned back in college.
Fascinating. Cross disciplinary cooperation and investigation.
So are these only found in areas where the lava flows were quite brief? I can't imagine a long flow not filling in the holes after the trees burnt up.

Great question. So the lava wraps around the tree and the tree eventually burns and dies. The charred tree likely stays in place, filling the hole for days to maybe a year or so until it succumbs to the wind and weathering in general. At that point, the hollowed tube where the trunk used to be is present. Remember also that many lava flows can inflate initially but then drain as the supply of lava wanes so that the lava would never fill in the hole. Obviously if there was another eruption, it could fill in the hole, which is why lava trees are somewhat rare.

I thought it was interesting that the holes remained deep. I would have assumed they would have filled up with sand or gravel over time.
I would call them lava ghost trees.

Moon is correct, in another short five hundred billion years it will be. Rock in Brother👍🏼❤️
