1954 Map of Trigo Peaks

USGS Topo · Published 1955

About this map

The Dome Rock Mountains and the jagged ridges of the North Trigo Peaks dominate this mid-century desert landscape within the Military Reservation. This terrain is defined by a complex network of seasonal drainages, where Trigo Wash and Mohave Wash cut through the arid plains toward the Colorado River valley. The geography here is marked by essential water sources for desert travel, including Mohave Tanks and White Tanks, which historically provided relief for those navigating the old trails between the peaks. In the southern portion of the map, the Chocolate Mts rise above the McAllister Wash, while signs of mineral exploration appear at the Tweed Mine and various unnamed prospects. This 1954 revision documents a network of primitive transportation routes, including the Mohave Road and the Gila and Salt River Base Line Road, showing how travel was managed across the La Posa Plain through natural gaps like Felipe Pass.
