So, this was an accidental first ascent, an AFA if you will. I was waiting for the two other guys to finish climbing The Flaw and was soloing some easy stuff on Diamond Head and this looked like fun. I didn't realize that it was undone until Tony Bubb pointed it out after the fact. Anyway, climb a hanging, left-facing dihedral just right of Diamond in the Rough. Top out on the same point and belay on gear. Downclimb the back for 20ft, then scramble around the left side to descend.
