1939 Map of Trigo Peaks

USGS Topo · Published 1939

About this map

North Trigo Peaks and South Trigo Peaks dominate this arid landscape, surveyed in the mid-1930s before modern development reshaped the Southwest. The terrain is defined by complex drainage networks like Trigo Wash, Mohave Wash, and Gould Wash which cut through the Dome Rock Mountains and the Chocolate Mountains. A primary surveying landmark, the Gila and Salt River Base Line, bisects the map, providing a critical reference point for territorial land division in the region.
