About this map

Spangler Hills and the northern edge of the Searles Valley define this desert landscape during the early 1970s. The map illustrates a transitional zone where industrial extraction and military operations meet the arid basin. Extensive mining activity is evident along the eastern slopes of the hills, particularly at the St Elmo Mines and the Stephens Holding Mines. These sites, accessed by the Stephens Mine Road, represent the enduring mineral interests of San Bernardino County.

Transportation and infrastructure are dictated by the terrain, with Trona Road and several washes, such as Trona Wash and Teagle Wash, carving paths through the valley. The northern portion of the sheet is dominated by the Naval Weapons Center, with its boundary clearly delineated south of China Lake. Small-scale aviation is represented by the Valley View Airpark, positioned near the western map edge, serving the remote local community.
