1985 Map of West of Broadwell Mesa

About this map

The desert expanse between the Cady Mountains and the Bristol Mountains defines this 1985 provisional study in San Bernardino County. The map documents a landscape shaped by both geology and industrial transit, featuring the northern reaches of the Mesquite Hills and evidence of earlier infrastructure. A clear Old RR Grade cuts across the basin, providing a distinct record of historical transport routes that preceded the modern Transmission Line corridors. This mid-1980s data, compiled from earlier aerial photography, captures the arid transition between mountain ranges where isolated human activity is marked by a single Prospect in the northeast. The document is particularly useful for identifying the precise path of the former railroad grade as it relates to the surrounding topography and township boundaries.
