The lower level of Major Mass is bounded on the East by the formation that culminates in the Keyhole, a smaller version of the Doorway. Hammer Wall is the large, clean expanse of rock that faces East at the bottom.
The approach that requires the least effort is to hike up the Potholes trail, and cut West across the boulder field where the trail emerges from the trees below Red Rocks. There are currently (summer 2011) some massive old logs down along the trail just where you leave it.
