"The ascent of the two cathedral spires across the valley from El Capitan were the most difficult and adventurous climbs accomplished during the 1930s. After several attempts over a six month period. Robinson, Leonard and Eichorn reached the top of the Higher Cathedral Spire in April 1934, and they accomplished the Lower Spire a few months later. Steep and tricky climbing characterized both routes, and the trio had to use direct-aid techniques in a few spots when the hand holds disappeared."
