About this map

Antelope Acres and the surrounding high desert landscape are defined by a network of ranching outposts and agricultural research sites in the late 1950s. The map illustrates a transition from the grid-patterned valley floor to the geological complexity of the San Andreas Rift Zone. Several named family estates, including the Eric Munz Ranch, Cochems Ranch, and Pitchfork Ranch, are scattered throughout the territory, highlighting the area's rural heritage.

Institutional presence is marked by the Univ of Calif Agricultural Field Station and the Del Sur School. To the south, the terrain rises into the Angeles National Forest, where landmarks like Johnson Summit and the Ritter Ridge overlook Amargosa Creek. Infrastructure of the era is evident in features such as the Landing Strip, a Sanatorium, and various water-related markers like Willow Springs and several tunnels.
