1945 Map of Big Maria Mtns

USGS Topo · Published 1945

About this map

The Big Maria Mountains dominate the western half of this 1945 survey, showcasing the sharp topographic relief of the Mojave Desert region. Along the eastern edge, the Colorado River serves as the natural boundary between California and Arizona, flowing past the Colorado River Indian Reservation. This map, prepared by the War Department and the Corps of Engineers, U. S. Army, illustrates a desert landscape defined by transport and water. Human footprints are concentrated along the river corridor and major transit lines, such as the Atchison Topeka & Santa Fe railroad in the southwest and the Old Blythe Vidal Road in the north. Notable landmarks include Quien Sabe Point and Hills Ranch, providing fixed points for local history research in this arid environment of Sand Dunes and peaks like Black Hill.
