Geology professor Shawn Willsey explains the geology exposed at Shoshone Falls in the Snake River canyon near the city of Twin Falls in southern Idaho. Investigate the volcanic rocks (some tied to the Yellowstone hot spot) and fascinating geologic story exposed in the walls of the canyon. This is the second of a two-part video on the area. The first video provides an overview of the Snake River, Shoshone Falls, and the rocks that make up the canyon's walls.

Shawn: your field videos are an order of magnitude better than any in class Geo lab. Thanks for doing these!

@shawnwillsey 2 года назад

Hey thanks Dan. I appreciate you watching and learning with me.

I never did geology, but it was so interesting listening to Shawn showing us there are so many clues to explain this rock formation.

@johnshields6852 2 года назад

Very cool, the Earth's formation and deformation is so fluid, but it's timeline is vast, our quick time on earth doesn't get to see the movements, so it's great to watch you explain the terrain around you, puts it in perspective we can see.

Great breakdown of the layers and interpreting what was possibly taking place.

Great two parter! Fascinating story, thanks for telling it so well.

Thank you for the videos. Good ole Nick Zentner follower here. He turned us on to you.

@shawnwillsey 2 года назад

Awesome. Nick is way more ambitious than I but we share a common passion of sharing Earth's stories with others.

Wow, so much going on and each layer has a story. Thank you again.

You are so welcome!

The geological timeline is so vast, it is hard to comprehend. Our lives are so short in comparison. Amazing what is below our feet. That is a great area to see some of it. Thank you! Great video.

I’m learning…. Been able to identify my rocks with your teaching… you really are a great teacher thanks shawn

I never had geology but now I wish I had. I find it so interesting. I’m 77 and trying to keep my brain active. I’m enjoying the exercise.

@johnschmitt7957 2 года назад

Thank you, these are really well done. The wide-angle overview to roadcut details and interesting diversions works, the scenery is stunning and geology fascinating and well presented. Not sure how but I wasn't aware of these falls and now it's on my list.

@shawnwillsey 2 года назад

Thanks for watching and your kind words. Look for more new videos soon including a big surprise.

Interesting as always! You say it can't be knapped, but it doesn't mean I won't try. 😁

@shawnwillsey 2 года назад

Let me know how it goes.

@davidk7324 Год назад

You're right Shawn. I did just drive up/down the road focusing on the wetlands and springs. I'll do some geology exploring next time.

@ericchristiansen4823 Год назад

Nice explanations.

It would be cool to see you stop by the Black Rock Volcanic Field the next time you are passing through Utah

@shawnwillsey 2 года назад

Yes, I know that area. I will add to list and try to get to it sometime.

@ryanstropicalplantsoutdoor1989 2 года назад

I found your show a couple weeks ago watching 2 minute geology.... I started following you because it seems like he goes by the 1970s thinking and you are outside the box....no disrespect to him, I still appreciate everything I learned..... The next time you have a hard time getting your phone to focus make sure the background is completely out of frame and your phone will automatically adjust😁

@shawnwillsey 2 года назад

Hey welcome aboard and thanks for your comments. I am nowhere nearly as ambitious as Nick about doing these things but I do have fun with this niche. I use a GoPro camera to record, not a phone. I am sure my terrible videography skills need some work but I am trying to improve as I go. Be sure to subscribe and enjoy the existing videos as well as future ones.

@ryanstropicalplantsoutdoor1989 2 года назад

@@shawnwillsey I subbed first video... Even with the grow pro... I understand not being able to see the frame just keep in mind if the cameras trying to focus on the background more than the foreground you're always going to have a problem with texture.... Regardless...ill be watching

If the Basalt was flowing into water, why did it only form vesicles and not pillows?

@StereoSpace 2 года назад

The breccia layer at the base of the stack, to my eye, strongly resembles a pillow basalt. Especially the rounded knobs that protrude here and there and the powdery infill between the pillows. Let's call it a shattered and eroded pillow layer. Considering what lies above, the stream deposit, this may be a river valley flow.

@shawnwillsey 2 года назад

The breccia is most definitely not pillow basalt. The gravel and boulder fragments are composed of vitrophyre/rhyolite, not basalt. They also do not have glassy rinds around their edges like pillow basalt. Most of the breccia fragments are angular to subangular (not rounded).

@darrellid 2 года назад

Howdy, Shawn. As a SE Idaho resident and casual student of geology, I enjoy your content. Do you possess any interest in tuffs and other pyroclasts? If you like to combine geology and fishing in one outing, I could show you some.

@shawnwillsey 2 года назад

Thanks for watching and glad you are enjoying these videos. I love volcanic rocks in general but am not really one who enjoys fishing (too many boring memories as a child) although I should probably try fly fishing one of these days. Too many hobbies...

@petermedcalf5372 Год назад

Hi Shawn, when you say the rounded stones in the matrix were laid in a stream is it likely that the water was fast flowing or slow flowing to round the inclusions? And if so, is it more likely to be river rather than a strream?

@shawnwillsey Год назад

This would be a fairly rapid moving stream to transport and deposit golf ball sized rocks. Collisions between rocks caused them to become rounded.

@gerrycoleman7290 2 года назад

I wonder why the basaltic lava flow going into the body of water did not form palagonite.

@shawnwillsey 2 года назад

Great question. My thought is the stream was quite shallow, maybe a foot or so at the time of lava inundation. Also the lava flow was quite thick, maybe several feet (and likely inflated to its present thickness of ~30 ft). That would explain the glassy base and vesicles.

@gerrycoleman7290 2 года назад

I get so tired of language and it changing!! I was always told it was "Sho- sho-nee". SO, now it's "Show-shone"?

@shawnwillsey 2 года назад

In this region, it is pronounced as I presented it. There is even a town north of Twin Falls called Shoshone. And even the Shoshone-Bannock tribe in the area call it this way. Maybe its changed over time. I don't know.

@Anne5440_ Год назад

Both pronunciations have been around since the 1800s. I learned that there were 2 pronunciations when I first studied Lewis and Clark in grade school back east in the 1950s. After I moved out west in the 60s, I learned more about where the two pronunciations were used. As mentioned in other comments, using Shoshone (show shon knee) is the respectful use when referring to the native cultural group.
