1973 Map of Spangler Hills East

About this map

The Spangler Hills dominate the western landscape of this mid-1970s survey, marking a transition into the vast desert basin of the Searles Valley. This map captures the area's significance as a military installation, with a substantial portion of the terrain designated as the China Lake Naval Weapons Center. The topographical detail reveals a land defined by ephemeral drainage systems like Randsburg Wash and Teagle Wash, which flow toward a central depression. The infrastructure of the era is represented by the Trona Road and various Jeep Trails, providing access to isolated desert points. Minor industrial and exploratory marks, such as a Borrow Pit, a Prospect, and a Dry Well, hint at the sporadic mineral interest and water challenges common to this arid San Bernardino County region.
