1943 Map of Devils Heart Peak

About this map

Sespe Hot Springs and the drainage of Sespe Creek dominate this 1943 survey of the northern Topatopa Mountains. This map, published by the Geological Survey and mapped by the Army Map Service, documents a remote wilderness landscape defined by series of high mountain flats and intermittent water sources. Named flats like Coltrell Flat, Pigeon Flat, and Squaw Flat represent pockets of relatively level terrain amidst the sharp elevation changes of the Los Padres National Forest. Cultural features are minimal, though a Lookout Tower is noted atop Topatopa Peak, overlooking the Sespe Wildlife Area. The network of springs, including Buckhorn Spring and Dripping Springs, highlights the essential water points for cattle or early travelers in these arid high-country canyons. The map serves as a detailed record of the Ventura County backcountry before modern recreational development, capturing a landscape largely untouched by significant infrastructure.
