Description Suggest change

This is the creatively named 200 foot high, 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 Suggest change

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.
