BETA PHOTO: Cripple's Crack is second from the left
Climb the crack (the left of the two here). There's a small, triangular roof about 2/3 of the way up. Go around the right side of that. There's another roof about 3/4 of the way up, and stay to the left of that. Then it's a slab climb to the top.
Hades Heights, just as you turn the last corner before the path ends
