About this map

Santa Rosa State Park dominates this wartime landscape, stretching across the high elevations of the Santa Rosa Mtns where Rabbit Peak marks the boundary between Riverside and San Diego counties. The terrain drops sharply from these peaks into the Coachella Valley, meeting the northwest shore of the Salton Sea at an elevation of 250 feet below sea level. This 1942 survey shows a sparse but functional desert infrastructure, including the Oasis Maintenance Sta and Flemming Saw Mill near Fish Springs.

The Toro Indian Reservation is segmented across the lowlands, interspersed with vital water sources such as Coolidge Springs and the desert oasis at Seventeen-Palms. Transportation is defined by early routes like the Truckhaven Trail, which cuts across the Clay Hills and numerous seasonal drainages like Palm Wash and Arroyo Salada, reflecting a landscape where movement was dictated by the harsh geology of the Colorado Desert.
