As the years have passed, the Farallones have not grown any safer. For example, in 1921 the U.S.S. Conestoga sank in the perilous waters off the islands with the loss of all 56 hands. For decades, its fate remained a mystery until researchers from the National Oceanic and Atmospheric Administration spotted the wreck some 190 feet beneath the surface.
