The Green Monster Slab is a tall, sheer, west-facing face split by an obvious hand crack and several thinner, less continuous cracks. Green Monster and Erase Your Face are classic routes running up the slab's face.

Walk up the canyon from the parking lot for about a four-tenths of a mile. After the small chlorine treatment building on the right, and just before a north-facing alcove (The Kitchen), turn right on a trail and head south and uphill. The Green Monster is the second west-facing slab on your right (the first is the Bolt Slab).
