you need to learn how to use Google's reverse image search. drag and drop them in a google image search and it will give you the high res you want and locations. The first is first is Burlingame Canyon and the second is Mt. St. HelensBarbarian asks:
The Coconino sandstone is made of great deposits of eroded rock, forming desert dunes, which were subsequently buried and hardened.
How did this get formed in soft sediment by very fast moving water?
The image is to small to tell, but it appears not to have eroded out. Normally, canyons have a stream running through them. Got a higher-res shot?
It appears to be a gully, in soft sediment. It looks a lot like the gullies I saw at Mt. St. Helens from soft volcanic ash; again, it's a bit difficult with such a low-resolution shot,but it appears that the walls of the gully slump if they get more than a few meters high. Do you have a better image?
If you can get some closer, better resolution shots, we can probably figure it out. You do realize that the Earth is constantly reworking the crust and it would be astonishing to find a 4 billion year old canyon on it, do you not?
And could you answer my question?
