1984 Map of East of Valley Mtn.

USGS Topo · Published 1985

About this map

The Bullion Mountains dominate the northern terrain of this Mojave Desert landscape, casting a sharp contrast against the organized grid of roads and infrastructure to the south. This 1984 provisional survey illustrates a transition between the rocky highlands and the flat basin, where industrial and utility markers like a major Gas Pipeline and various Prospect points suggest a history of resource exploration. Local transit is defined by a network of named desert tracks, including Amboy Road and Shadow Mtn Road, which provide access to this arid interior. Of particular interest to researchers are the Diversion Dams and scattered Ruins located near the southern sections of the map, indicating previous efforts to manage water or establish settlements in this challenging environment. The alignment of roads such as Virginia Road and Chadwick Rd reflects a sparse but deliberate human footprint across the San Bernardino County desert floor during the late twentieth century.
