Anza-Borrego State Park's name is derived from Juan Bautista de Anza, who notably camped there, and "borrego", which is Spanish for "lamb", in honor of the local herds of bighorn sheep. The area east of town was the site of a vast World War II US Navy training center, the Borrego Valley Maneuver Area, with supporting camps and airstrips.
