1984 Map of East of Leach Lake

USGS Topo · Published 1988

About this map

The high-desert terrain of the Avawatz Mountains dominates this 1980s topographic study within the Fort Irwin Military Reservation. This survey, compiled from late 1970s aerial photography, captures the stark geography of San Bernardino County before modern developments altered the access patterns of the region. The map tracks numerous 4wd routes that thread through steep contour intervals, reflecting the difficult navigation of this protected military landscape. In the southern reaches, the dry basin of Drinkwater Lake provides a rare level landmark among the complex ridges. Several vertical control stations, including BM 2546 and BM JRH 34x, are carefully plotted, providing precise elevation data for geologists and desert researchers studying these arid slopes.
