Description

Up and right from the Dairy Queen Wall is this nicely featured wall with a good assortment of mostly crack routes and the odd face climb. Highlights here include Tax Man (5.10a) and Alf's Arete (5.11a). Morning sun and afternoon shade.

Getting There

Approach as for the Dairy Queen Wall but head up and right through boulders following a worn path to the base of the wall. Plan on a 15-25 minute approach from the car.
