Revillagigedo High Sea

The eastern Pacific north of the Revillagigedo Islands separates their volcanic peaks from the peninsula of Baja California. The islands of Socorro and San Benedicto were reached by Hernando de Grijalva's expedition in 1533, when they were named Santo Tomás and Los Inocentes. Their rocky landfalls stand far from the mainland, surrounded by waters where seabirds find food.
