"Wiessner spotted two possible lines, so they continued to the face and gained a large ledge, the "Traverse Ledge" which traverses almost all of the face at the top of the lower dirty wall. They continued south along the ledge until they came to the further of the two possible lines, which they then climbed."
They had driven up and parked below, picked out two lines and scrambled up through the talus field. Moving south (from the right) and then climbing the "Old Route" they started it all 74 years ago.
Ironic how with the 75th anniversary of Gunks climbing almost upon us, that we can't climb on half the rock out there..... legally. RC
