Dan Sedenquist weighed in, (former Geologist):
"...The second photo looks like a volcanic welded tuff (Chiricahuas is a good guess). Bandolier Natl Monument?.."South of what? Or do you mean The South? Plants don't look right for anywhere in the South.Pfemm: Other than it is in the south :)
It still doesn't look right to me and the "South" reference would seem to nix this article I found...The Disappearance of Mount Mazama published in 1901 about the mountain that used to exist where Crater Lake is found today.1901 eh?
