1966 Map of Mount Triplet

USGS Topo · Published 1968

About this map

The San Carlos Indian Reservation dominates this 1966 topographic study, characterized by a complex network of ephemeral drainages and livestock water management. High points like Mount Triplet and Salt Mountain overlook a landscape carved by Hackberry Creek and Triplet Wash. The reliance on local hydrology is evident in the numerous named water sources, including Hackberry Spring, Willow Spring, and Salt Spring, as well as improved locations such as Saguaro Well and Double Tank. Human activity is concentrated around the Salt Creek Ranch Hdqrs in the northeast and a series of Borrow Pits and prospects that suggest small-scale material extraction. This map documents the essential infrastructure of ranching and resource management within the reservation during the mid-1960s, prior to significant modern development.
