1987 Map of Eagle Crags

USGS Topo · Published 1987

About this map

Eagle Crags dominates this high-elevation desert landscape in San Bernardino County, which by the late 1980s was largely encompassed by the Naval Weapons Center. The map provides a detailed look at the scattered water sources and traces of human activity in this arid environment, including Blue Chalcedony Spring and the Moonshine Spring (Dry). Evidence of early twentieth-century activity persists through labels for a Prospect and clusters of Ruins located near the northern springs. The terrain is marked by significant elevation changes, with several peaks noted by survey markers, reflecting the complex topography utilized by the military for testing and training. Remote outposts like Mesquite Spring sit along unimproved roads, illustrating the limited infrastructure of this protected desert range during the late Cold War era.
