About this map

The Tohono O'odham Indian Reservation dominates this desert landscape, where the flat floor of the Santa Rosa Valley meets the high, rocky elevations of the Santa Rosa Mountains. Evidence of early surveying and land management appears at GLO Station 19, while the topography is defined by the braided paths of the Santa Rosa Wash and Sil Nakya Wash.

Mineral exploration is concentrated near Gu Achi Peak, where a Mine Shaft, a Prospect, and several Drill Holes indicate a history of geologic sampling. For those interested in cultural sites, the map identifies the Makgum Havoka (Site) in the southern valley. This 1996 update, based on 1961 topography, preserves the locations of essential desert water sources like the Mule Shoe Tank and scattered corrals, illustrating the area's ongoing use for cattle grazing within the reservation.
