Hey Alois ~
Are there any reported routes on the center of that buttress. It looks like something could go....
No Dave, I'm not aware of anything else on the buttress. But a word of caution. If you are going to carry all the gear up the canyon, there is a ton of other possibilities up there that dwarf this ten pitch thing. It's a bitch of an approach to go there just for this climb. As you know, the South Face is over a mile wide and there is still a lot of climbing to be done there.
