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 climbs here tend to have an "old school" feel to them and may seem runout to those unaccustomed to such routes.


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.

Looking back up the start of the standard descent.  The anchors for Let it Bleed and Cheap Thrills are just out of sight, past the skyline of the rock in the center of the pic.  You can see the lightened streak from foot traffic, coming down from the top of the large flake.
