California, Gulf of

Gulf separating Baja California from the rest of Mexico. Its area is about 59,000 sq mi (153,000 sq km). Its waters were coloured by red plankton when 16th-century Spanish explorers named it Mar Bermejo (“Vermilion Sea”). Some geologists hold that the gulf is structurally part of the Pacific Ocean; others claim Baja California is pulling away from the continent as it moves north along the San Andreas Fault, allowing the gulf to form.
