 Gallwas described his relationship with Robbins and Wilson as teenage amateurs in tennis shoes.At Tahquitz (Lily Rock), the three honed their skills and dreamed of big climbs to come.The vision started to become a reality when, in 1953, the three made the second ascent of the North Wall of Sentinel Rock.Robbins showed little interest in desert climbing, so Gallwas teamed with Wilson and Mark Powell to make a series of pioneering first ascents of sandstone spires in the American Southwest.
