Description 

This is the creatively named 200 foot, west-facing granite slab which is the focal point of the area. Almost all of the routes here are easy to moderate slabs with the odd crack thrown in for variety. Despite the easier ratings the climbs here tend to have an "old school" feel to them and may seem run-out to those unaccustomed to such routes - caveat emptor.

Getting There 

Park in the fee parking area and hike in along a paved service road to reach the obvious west-facing "big rock". Plan on a 10-15 minute approach from the parking area.
