Yeah... that view was covered with smoke when we were there.

I'm looking at the striations in the rocks near the peaks of the mountains there, I see horizontal-ish lines highlighted by the snow, apparently layers of rock laid down first. Then the vertical-ish fractures, like knife cuts through the layers of rock making thick slices leaning to the left of the highest peak. The talus covered slopes in the foreground were all part of the higher elevations at one time and crumbled away forming the base of the mountain.

Of course, no knife cut through the stacks of layers of rock.

These patterns were made when the layers of rock we see were all continuous and flat and horizontal. Then titanic forces pushed upward producing the elevation and fracturing we see here.

I've been moving some concrete around the yard for some projects. I'm breaking up the anchoring of a gate frame and I'm arranging some blocks. Some of the material is literally too heavy for me to lift, I can barely move it to get a good swing at it to chip away at the surface in an effort to make it small and light enough to maneuver. The key word here is "effort". That stuff is really heavy. It boggles my mind to try to conceive of the forces that raise up mountains of that material.

Awesome.

There are a lot of stones here which would look great in the yard but granite goes about 168 lbs per cubic foot. The lift on the tractor barely wiggles them.

I have had friends who would tell me "ROCKS DON'T BEND."
I imagine they are all off MAGAing now.

That is pretty cool, DJ.

It kinda irks me a little when the APOD is not something in space (outer).

Cool pic, and all...

The picture has been kicking around the net for at least 5 years.

Tripod & chain fall, or engine hoist, then slide a wagon or truck or stone boat under 'em.

You seem more determined than I feel. :D

Get an old jon boat. Tilt the boat over on its side, roll the boulder into the boat, tip the boat flat, drag it where ya want the boulder, roll the boat onto its side, and roll the boulder out.
