The Cornerstone is a large formation located in the far reaches of the Wonderland Valley. It's home to a fine assortment of face and crack routes including As the Crags Turn (5.7), General Hospital (5.9), All My Children (5.8) and Tomato Amnesia (5.10a).

Getting There 

Follow directions to the Bighorn Dome, continue down the valley about .5 miles, generally following the wash. The Cornerstone will become obvious on the left side. The east side of the formation can be identified by the left leaning flake system ( "As The Crag Turns" ) and the large flake system which splits the face ( "General Hospital" and "Rope Opera" ).

This route is a bit serious for the 5.9 climber but well worth climbing if in the area. The start is hairy with little pro and extremely thin flakes for holds.

The top of the flake section of the climb can be protected with small cams in a ...[more]   Browse More Classics in California

This rock is a good hour hike/scramble from the Wonderland Parking Area. Worth the time to climb if in the area. This and other far flung Wonderland destinations are probably better done as a short backpacking trip on a weekend instead of a day hike.

This crag, or any Wonderland crag, can easily be climbed in a day trip. There is a really good Bighorn sheep study going on in the Wonderland and it is therefore illegal to camp there. One of the controls of the study involves keeping humans out of the area at night.

Ryan - the routes in this portion of the Wonderland are perhaps more easily done as a weekend backpack trip, however the Wonderland is designated as day-use only. Spend the time to learn the terrain and more importantly - hike faster!
