1958 Map of Del Sur

About this map

Portal Ridge dominates the southern landscape of this 1950s survey, marking the dramatic transition where the San Andreas Rift Zone carves through the terrain. The map details a rural economy defined by sprawling cattle and agricultural operations, including the Eric Munz Ranch, Cochems Ranch, and Pitchfork Ranch. Settlement is concentrated around the Del Sur area, supported by the Del Sur School and the Univ of Calif Agricultural Field Station. The geometric grid of the Antelope Valley is visible in the north, featuring the early development of Antelope Acres and the Sanatorium. This era represents a time before significant suburban expansion, where water sources like Willow Springs and the seasonal flow of Amargosa Creek were central to life. The southern edge reaches into the Angeles National Forest, where topography rises sharply toward Johnson Summit.
