The Gill Boulder lies next to a shady picnic area right after crossing the last bridge in the canyon. There are multiple problems on every side of this massive boulder, and most of them are "classic status." Though some of the lower holds on the easier problems have been greased to baking pan standards all are worth climbing. Descend this boulder by using the tree on the east side.

Getting There 

Park on the right in the picnic area just after the final bridge in the canyon. The Gill Boulder is left of the lot, 10 yards away.

Anyone know what the line is just to the right of the North Dihedral? I climbed it today from a stand and sit. It's pretty fun, V1, I guess?

Anyone know the problem in the center of the south face, to the right of Gill Face and left of Southeast Slab? It's just two crimpy moves to the topout.

On here it's called South Face (V4). Anyone know what the NW corner problem (left of Horan's face) is?
