Georef. RemarksCoordinates at Guadalupe Island, Islas Revillagigedos are a few hundred miles south of Guadalupe. In 1925, the California Academy of Sciences (San Francisco) mounted an expedition to explore the Revillagigedo Archipelago off the Pacific coast of Mexico (Hanna 1926). The U.S. Navy generously provided the ship, the U.S.Ortolan, a mine sweeper. En route to the Revillagigedo Archipelago, the expedition spent three days at Isla Guadalupe (19–22 April 1925).
