Cave Canyon, San Clemente Island
“The first canyon west of China Canyon is apparently unnamed, the second is Red Canyon, and the third, a very large canyon draining nearly due south from Thirst and with its mouth just off the quadrangle, is Cave Canyon.” [Raven, Peter A flora of San Clemente Island, California Aliso 5(3): 289-347, April 15, 1963]
