Higher Cathedral Spire, Northwest Face. The first ascent was made on June 6–7 by Tom Frost and Royal Robbins. This route involved eleven pitches, 180 pitons and six bolts. One of the pitches took five hours to complete and needed 36 pitons and four bolts. Two previous attempts had been made on this 1100-foot face. The climbers regarded this ascent as difficult as the northwest face of Half Dome.
