Chimney Rock. One of the milestones along the Oregon Trail (which runs along the North Platte River marked by the tree line at the top left of the frame). November 2, 2024 (a few days before the big snowstorm that swept the west).

What a fascinating geological formation. When I see things like this, I wonder what was going on in the past which allowed such a happening. The sedimentary layers indicate this entire area must have been under water for a long time during the distant past. Did the water recede or did the land mass rise?

I'm hoping God has it all on video and lets us watch the re-runs every Friday night after choir practice
 
These are sand dunes near Rexburg, ID. I didn’t know of their existence, and it was a pleasant surprise. Has anyone here explored them? They seem to be at least as large as the Great Sands dunes in Colorado.

I bet Bob Christensen has as he is from Rexburg!
The area is a big time destination thing for many, there's a huge scene there on the weekends, I'm not sure of the proper geological term for them, but yes they are unexpected when you see them for the first time!
 
This was west of Fontenelle Reservoir on 11/2/24. It’s a fairly remote area in western Wyoming, near the WY / ID state line. Any idea what’s going on here? Spreading manure or top dressing? Burning dad’s diesel? Large scale art installation? Bad ball joints? Too much Christmas eggnog? Inquiring minds want to know.

Mima mounds, eastern Oregon.

View attachment 109063
The borders of the mounds remind me of patterns I’ve seen in alpine tundra in Colorado. From what I’ve read, the freeze / thaw cycles move rocks into polygons. I wonder if similar forces are in play here.

edit: here’s what wikipedia says about them: “Theories for the origin of Mima mounds include burrowing by pocket gophers; accumulation of wind-blown (aeolian) sediments around vegetation to form coppice dunes or nebkhas; seismic ground shaking by major earthquakes, though none have been observed to form Mima mounds; and shrinking and swelling of clays in hog-wallow or gilgai landforms.”

Peter, here’s what Wikipedia has to say about the geology that formed Chimney Rock:

Geology​

Chimney Rock consists primarily of Brule clay interlayered with volcanic ash and Arikaree sandstone. The harder sandstone layers near the top have protected the pillar since it broke away from the retreating cliff line to the south.[9] Chimney Rock rises approximately 286 feet (87 m) above its surroundings.[1]

Where do you suppose the volcano was that produced the ash? The closest one I can think of is in Yellowstone. A note to Steve Johnson: we need a staff geologist, please.
 
Speedo, Here is an extensive discussion of the Nebraska geology. https://www.nps.gov/parkhistory/online_books/geology/publications/pp/17/sec2.htm
The volcanic ash could have come from a long distance away. I was in Anchorage after Mt Spurr erupted in 1992 which is 75 miles west of Anchorage. There was a layer of ash all over the place. Millions of years ago when the volcanic activity was more active it could have traveled hundreds of miles.

Thanks for finding that paper. For folks who follow the link, there’s a general overview of Nebraska geology at the beginning, and the details of Scott’s Bluff and Chimney Rock at the end. Very interesting stuff.

Hey Speedo, are you flying a Wilga? How do you like it? Space Shuttle fuel burn and cub speeds?

Close. More like Comanche fuel burns and cub speeds.

I’m having a great time learning the care and feeding of a Wilga and trying to master it. My landings are graceless. I spent all summer flying a PC-12 around 300 hours (and around that many landings) and I could really roll it on nicely. But with the Wilga it’s been more of a plop. Still don’t have the sight picture quite right.

Likely because you’re going too slow to roll it on. It has no choice at that speed. :)
 
Stan Herd created that art in the late 90’s. Living in that area we got to see a lot of his large scale works. One of the first to leverage gps for this kind of thing.
