1959 Map of Sombrero Peak

USGS Topo · Published 1960

About this map

The In-Ko-Pah Mountains and Tierra Blanca Mountains dominate this high-desert landscape in the late 1950s, revealing a region defined by isolation and sparse outposts. Settlement is concentrated at locations like McCain Ranch and Canebrake, while the presence of a Cem and an Airway Beacon on the slopes reflects the intersection of early pioneer life and modern navigation needs. The map captures the delicate environment of Anza-Borrego Desert State Park, featuring notable oases such as Sombrero Peak Palm Grove and Bow Willow Palms. Indigenous heritage is marked by the boundaries of the Cuyapaipe Indian Reservation and the Manzanita Indian Reservation. This survey highlights the era's reliance on rugged access routes, with numerous segments of Jeep Trail and the Pepperwood Jeep Trail providing the only means of navigating the transition from Indian Valley down through Rockhouse Canyon.
