1958 Map of Mustang Mountains

About this map

The San Ignacio Del Babocomari grant dominates the southern portion of this landscape, where the Babocomari River flows through the valley floor. In the late 1950s, the area remained largely defined by large ranching operations and the infrastructure of the Southern Pacific railroad, which skirts the southern edge of the mountains. The map illustrates a transition from the alluvial flats of Rain Valley to the prominent heights of Mustang Peak and Mt Bruce. Evidence of local travel and resource management is found in the Mescal Spring Trail and scattered livestock water sources like Cottonwood Spring and various water tanks. Working ranch life is anchored by established sites such as Rain Valley Ranch, Sands Ranch, and Babocomari Ranch, reflecting the era's continued reliance on the valley's grasslands and reliable springs.
