Make moves up the brownish face with good holds and horizontals for gear until you reach the slab. One Bolt protects the crux on the slab. There may be more horizontals that take gear after the bolt if your nervous, I just ran it out since the climbing is easy. Belay at the trees and rap off.
Not on the twilight buttress but on your way up to the twilight buttress, there is a granite slab 20 feet off the trail on the left. Hard to miss.
Standard rack to 3"
