About this map

The Roskruge Mountains and the northern tip of the Coyote Mountains dominate this landscape within the Papago Indian Reservation. This late-1970s survey captures a high-desert environment where water management is central to settlement, evidenced by a network of isolated wells and tanks like Townsend Well, Dill Well, and Reservation Tank. The small settlement of San Pedro sits along the western edge near a marked Cem, reflecting the local genealogy of the area.

Evidence of ranching life is visible through the U-Diamond Ranch and Coleman Ranch, which are positioned near drainage systems such as Mendoza Wash and Viopuli Wash. A Radio Facility atop Martina Mountain and the distinct volcanic forms of Dobbs Buttes provide prominent navigational landmarks across the desert floor, while San Pedro Road serves as a primary transit corridor through the reservation territory.
