2021 Map of Iron Ridge

USGS Topo · Published 2021

About this map

Iron Ridge rises above the high desert floor in this 2021 look at a remote corner of San Bernardino County. The landscape is dominated by the Rodman Mountains to the north and the broad expanse of the Upper Johnson Valley to the south, both part of the greater Mojave Desert ecosystem. This map documents a region where human presence is primarily marked by industrial and transit infrastructure rather than permanent settlements. Transport through this arid terrain relies on a handful of specialized corridors, including the utility-focused Transmission Line Rd and Bessemer Mine Rd, which likely serves historic mining interests in the surrounding hills. The map provides a clear record of the Public Land Survey System grid across these townships, showing how the desert was partitioned even in areas without traditional township development.
