Awesome! I've driven past that so many times over the past 40+ years. The layers in Ogden Canyon have always amazed me. When I was at WSU back in the 80s we climbed several spots up and down the canyon, lots of fun short routes.
Such a good Random Roadcut! I could see exactly what you were talking about, awesome to be able to so clearly see the fault! Thanks for putting this together for us!
Thanks for the Ogden Canyon heads up. Slickenlines/faults are all over the Wasatch. For those interested, see Shawn's Big Cottonwood video from ~1 year ago. Possibly an F-35 from Hill doing some aviation geology.
Random Roadcuts, Friday edition: always a great way to start the weekend! The thrust fault is easy to see and pretty spectacular. Thank you for this new episode of an awesome educational series, Shawn :)
Having lived in Eden for 20 years & driven past there many times thanks for looking at this area. There have been several moderate quakes where you were standing but on the Southside of the dam in the last 20 years. Where you were standing & looked to the south there is a verticle fault with 10'+ of displacement between layers I found years ago. My fireplace mantle & wall was built of that rock we carried off.
When I lived in Ogden in the mid - 1970s, a geology student friend pointed out some nice stuff in that area. Just downstream of the dam on the north side of the river is a very obvious z-fold and following the layers around it is a fun activity. Of course, the massive outcropping at Willard, seen from far away is an amazing sight. I have to stay focussed on driving when I go by because it's so distracting. Thanks for a new episode, and one with which I'm a bit familiar!
Please 🙏🏼 be very safe and watchful while doing these 😊 But I’m sure you already know that. ✨☺️ And wow 🤩!! On being able to show us what a thrust fault looks like 👍!! 😊
❤Just loved the episode! I learn so much from your shows. As an amateur with a healthy curiosity, I really appreciate the field work. Random Roadcuts open a whole new viewpoint for me. 😊Thx, man! 😎
I'm not super-familiar with the geology of Ogden Valley, but leave it to Utah to buttress a dam in such busted-up, carbonate-rich rocks. I hope the engineering experts who sited it there knew what they were doing.
Very cool, thanks Shawn! Question; what history would the repeated pattern of limestone/sandstone imply? At one point you mentioned the possibility of wind blown sand - water, desert, water?
Great video as always. The camera is doing some sort of color balance operation that gives distracting changes in color as you pan. Perhaps you can shut that off.
I sometimes am tempted to take the leftover loose rocks from road cuts for home landscaping, any idea if there would be a problem with that? I don’t know what they use to carve those out and if there is anything hazardous on the rocks
When you were at weber did you have yo measure and do a geo colum just down from the dam on the north side? I was disagreeing with my partner on weather he was keeping the crect bed contact veiwing it from the ground. I climbed up to follow the bedding with my hands on . A rock i steped on slid doen with me standing on it. My finger carving throught the soft shale beds like youd see in a cartoon . I steped of thr rock walked to my partner and said witb H dignity " i agree with your vision of the layers"
Is it just me or has the image quality of Shawn’s videos taken a dive recently? I’m seeing very low dynamic range, low color saturation and highly compressed video with high levels of artifacting. I don’t remember it being this bad in the past. I thought I would mention it especially in this video where he tells us how important color is in identifying a rock/minerals.

Thanks Shawn. Increase the contrast in the video, or a frame from the video, and those layers become much easier to see. The faults really stand out.
Awesome! I've driven past that so many times over the past 40+ years. The layers in Ogden Canyon have always amazed me. When I was at WSU back in the 80s we climbed several spots up and down the canyon, lots of fun short routes.
This area is where I lived for 35 yrs.
Finally I learned exactly what it was.
Incredible

You mean this Z fold? th-cam.com/video/G0swRYNbQ9Q/w-d-xo.htmlfeature=shared
@@shawnwillsey That is indeed the one. Thanks.

Nice!
Love the faults!
Would this have been a place that was sometimes ocean, sometimes beach sand, back and forth over the years?
Yes, exactly. Changes in sea level or up/down movement of land created different depositional settings (shallow water, beach, etc.)
Very cool, thanks Shawn! Question; what history would the repeated pattern of limestone/sandstone imply? At one point you mentioned the possibility of wind blown sand - water, desert, water?
Very nice work sir I'am Master in Geography but I like geology also I'am watching your video from Multan Punjab pk
Every time Shawn uses the pickaxe, I expect him to lick it like Yukon Cornelius to tell us what kind of rock it is. It's been a long day.
Great video as always. The camera is doing some sort of color balance operation that gives distracting changes in color as you pan. Perhaps you can shut that off.
Humbug formation and the Willard thrust is nearby…
I sometimes am tempted to take the leftover loose rocks from road cuts for home landscaping, any idea if there would be a problem with that? I don’t know what they use to carve those out and if there is anything hazardous on the rocks
There was a tunnel in that spot for years
Still there just below the road 50'
Is this an example of the Sevier Thrust?
Is there a particular reason that HCl is thepreferred acid for testing?
Would a hand lens help in identifying the rock types in the field ?
Always. But it's hard to look at rocks through hand lends while holding camera. Not enough hands.
What is the acid solution you are using?
Hcl
I hope it's not a very active fault, considering they built a dam right there.

Do you ever encounter snakeite? :-)

Why build a dam in a place that has so many faults?
As far as im aware as a utah resident, fault line are all along the mountains here. But the mountains make for good retaining walls.

I’ve been in that cave several times many years ago. It’s a tight one.
