1986 Map of West of Red Pass Lake

About this map

The Fort Irwin Military Reservation dominates this 1980s landscape, reflecting the heavy military presence in the High Desert of San Bernardino County. The terrain is defined by the sharp rise of the Tiefort Mts, where steep contour lines reveal a complex network of arid ridges and dry washes. Unlike typical civilian maps of the era, the land here is largely devoid of domestic settlements, schools, or churches, focusing instead on the topographical challenges of a training environment. Strategic water management and land modification are evident in the series of Levee structures positioned across the northern flats, likely built to manage seasonal runoff and protect maneuver areas from flash flooding. This map provides a clear view of the Mojave's natural desert geometry before more modern tactical developments on the base.
