Cortes Bank is a chain of underwater pinnacles and plateaus located 137 nautical miles (nm) South by Southeast from Santa Barbara and about 40 nm Southwest of San Clemente Island. Bishop Rock is one of the peaks in the underwater mountain chain that rises to within 6 feet of the surface and is marked by a nearby warning buoy. It was named for the clipper ship Stillwell S. Bishop that struck the rock in 1855 and with a patched hull limped its way back to San Francisco. Nine Fathom spot is about 4.5 miles Northwest of Bishop Rock and rises to about 60 feet below the surface. Both are noted scuba diving locations featuring clear water and abundant sea life.
