1985 Map of East of Broadwell Lake

About this map

The Bristol Mountains dominate this high-desert landscape in San Bernardino County, where industrial infrastructure cuts through a largely unpopulated terrain. Surveyed in the mid-1980s, the map reveals a pattern of mineral exploration defined by several scattered Prospect sites and Prospects in the northwestern quadrants, indicating a history of small-scale mining efforts. Running across the southern and central portions of the sheet are significant utility corridors, including a Trans Line and a long Pipeline that traverse the arid flats and lower slopes. These human-made lines contrast with natural drainage features such as the Wash that cuts through the southeastern corner, illustrating the intersection of modern utility expansion and the environmental reality of the Mojave desert.
