Oops! I goofed again. I thought the route was a Skytop route which I used to know as Between Plates C and D from the first Williams book later called Beardlings. I checked the route photos and now realize I was wrong. I now think it is route at one of the smaller undocumented cliffs. The photo is over thirty years old. I have other photos from that roll from Skytop and this other cliff (not Lost City or near Talus Food). Here is one that I'm sure of.
