Thanks Shawn. Have you ever visited the Great Blade? I'd like to see and hear your experiences and thoughts about it. It sounds as though it has an interesting history.
Random Roadcuts is so awesome! Highway 78 is one of my favorite drives, so I appreciate your stopping along there! Also, a few years ago I bought a slab of basalt with amygdules that are cherry-blossom pink and apple green. Don't know where it originated but I was charmed...someday I'll cut it and make a great big ring. Thanks for explaining how the stone formed.
There's a lot of detail in that road cut that you'd easily miss flying by at 55mph. The mineralized fractures are pretty neat. Perhaps that area was a hot spring many moons ago. Thanks for giving us something to ponder.
Thanks Prof. Shawn. I have no idea how many times I’ve been past this road cut while photographing and just plain having a Sunday drive. I guess it’s time to fill up my pickup and grab my camera and rock hammer and take a drive.
Thanks Shawn. Mineral laden hot springs are not uncommon in the area, present day Givens is up the road just a few miles, I think. I hunted arrowheads around that area in the 60s.
When I first saw those amygdule, I figured it was material blown in by the highway dept. to fill spaces between rock and/or layers. Kind of like that concrete blown on steep angled highway cuts and meshed with a metal wire interface.
I really enjoyed this video and learned something as always, but as you’re so often out in windy places like this, please if you can try to invest in a wireless microphone which has better protection from the wind for increased sound quality. Your videos are great, but the sound quality could do with some improvement. Thanks as always for sharing fantastic geology Shawn!!
Thanks for another episode in our local geologic history. I'd love to hear your interpretation of the massive road cut on US 95 at about mile 13, at the top of the Marsing grade. It's one of my favorites...there's SO much different stuff to look at.
Couldn't help but notice a large 800 foot wide volcano 2 miles southeast of here as well as another smaller one 1000 feet to the northeast seen on google - earth. Very interesting road cut with many things that have happened here millions of years ago now exposed. Not surprised there was zeolite deposits amid the crumbly volcanic rocks. There are 2 abandoned mineral mines to the west of here. Nice roadcut professor!
@@shawnwillsey Right, thanks! But isn't there a kind of basalt that can contain quartz, though...? I think I read something about it in an article... tholeiitic, something like that... Anyway, it's quite complicated for the layperson and I may just be mixing things up!
Hey Shawn. Can you do a video on the road cut on US hwy 95 just south of Marsing? Go to the rest area up on top of the pass. There is a yellow colored layer under the basalts. I am curious as to what it is.
Shawn The next time you are in Arizona in the middle of Kingman on Interstate 40 there is a huge cut on the north side of the road. I'm very sure you have seen it with the white layers and fault lines going through it. I believe if I read it correctly it is from the Peachtree Till. I guess recently they found a super volcano or two that area. That would be a great roadcut to explanation.
If I guessed I would say the gas in basaltic vesicles would be Sulfurous, but in reading it seems it is steam (H2O) and carbon dioxide, which seems odd if oxygen was in short supply many eons ago.
I so enjoy these videos. I have one wish. Is it possible to make the wind noise less? I am autistic and have hearing aids. Both make it hard to concentrate when the wind sound is there. ❤️
Really liked your explanation question if you’re still in Iceland any chance of a sample of new lava to study under microscope happy to cover shipping kind regards Bruce
A quite different kind of "Roadcut" (where a failure cuts a road), but I wouldn't mind seeing some sort of video about the soil and rock layers that gave way and took out Wyoming Highway 22.... Given the location, there was probably all kinds of interesting layers from wind, water, ice, and volcanism.
Interesting that the amygdules seem to be in layers separated by basalt layers that are free of amygdules (although there appear to be vesicles waiting for the deposits in the "blank" basalt.) Why are there no amygdules in these other layers? Did the water not penetrate that far or something, so the amygdules are maybe just on the top surface or the basalt? Also, my first thought about the white deposit on the near-vertical crack as you first approached the cut was some sort of lichen, rather than something of geological nature. Final "observation" - I had always thought of igneous rocks would be very hard - maybe I'm just thinking of obsidian (or maybe I'm just transplanting my Minecraft knowledge!!)
If I direct you to a movie on RUclips, with this specific scene that has an interesting rocky terrain, can I ask you a geological question you might have the answer to?
There's a road cut going south west on hiway 26 as it drops down into the Conant valley, that I've always wondered about. It looks like volcanic ash or a pyroclastic flow.

The beginning of every roadcut I say, Wow! They provide a lifetime of wonder. Thanks Shawn!!! 👏🏻👏🏻
Shawn Willsey, Your videos always brighten my day, so I subscribed!
So cool. Thanks! Enjoy the existing videos.
I Love the way you make sense out of what we're seeing. It gives me so many more observational tools when I'm out & about.
The road cuts are always so educational. Congratulations on getting to 106k.
I hate to be needy, but I was starting to get the shakes from random road cuts withdrawal. :)

Another cool story to tell…..Thanks, Shawn! 👍
Thank you!
comfy videos! I found you through your Craters of the Moon videos and stayed for the geology!
Shawn, what you were describing @ 9:30 looks more like a lava toe. just my observation of the feature. Thanks for your service and video work. Cheers.
Thanks Shawn for the very interesting road cut. I sure need to get out there someday. Hope you are enjoying Iceland right now.
My favorite video series.

Cool! We saw some very similiar cuts outside of Pendleton on the NAGT field trip in 2022. We also had some mini columnar jointing in the lower layers.
Thanks!

Love the Random Roadcuts. Please get a microphone with a windscreen, though. 🙂
I think he might be willing to accept a donation.

Thank you enjoyed your video
Yes! Saturday night's Random Roadcut! 🤗 Love it, thank you Shawn! Could it be quartz that fills the amygdules...? 🧐
Hi Sandrine. Likely not quartz since these are basaltic rocks (which do not contain quartz).
@@shawnwillsey Right, thanks! But isn't there a kind of basalt that can contain quartz, though...? I think I read something about it in an article... tholeiitic, something like that... Anyway, it's quite complicated for the layperson and I may just be mixing things up!
Interesting, the basalts in Victoria usually have clays and a calcrete band in the formation, but not weathered like this. Must be climatic factors.
The vocabulary of a geologist is extraordinary. I mean, AMYGDULES! Come on!
Amygdala is a portion of the brain that governs response to perceived threats. It comes from the Greek word for almond.
I'd like to see you read the rocks on the Mars Perseverance rover photographs.

*@**3:45**, Shawn you have evidently misspoke, "more viscous" means less runny and more thicker, "not runny"?*

What is the difference between Amygdules and Varioles?
Amygdules specifically form in the vesicles (gas bubbles) of volcanic rocks.

I have a feeling this hill is not a road cut. Just a natural basalt hill next to another hill that joins a roadway on highway 178
Hey - Are you in Iceland now ?
Yes indeed. Until May 30.
@@shawnwillsey Terrific ! Gylfi has been eagerly anticipating your visit as well as we, his subscribers have ! Can't wait to hear !
Common opal weathers into a white color & often retains its waxy luster.
👍
Is that rhyolite ?
No basalt.

Looks a lot like masonry repairs!
