And I appreciate the explanation of the red granite stained from slate. I was in the Grand Canyon about 35 years ago and on Tanner trail, in a 'micro canyon' we wandered into along the way, one wall of it was red and the other blue. A very cool effect, I had no idea then how it did that. More vagaries....
Love the phrase ' vagaries of cementation'.

I loved Canyonlands - but also have a slot canyon in Permian red desert sandstone 1/2 mile from my house here in Nithsdale, Scotland.
That's great!
Spectacular Google Earth image of the multiply fractured arch!
I think there is a small one in the reddish sandstone west of Oklahoma City,. It is choked with trees however.
