Santa Rosa Wash and its various tributaries, including Bitter Well Wash and Kohatk Wash, define the drainage patterns of this arid landscape in the Sonoran Desert. The map documents the scattered settlements of the Tohono O'odham Nation, centering on Tat Momoli, North Komelik, and the small community at Kohatk. Toward the northeast, the terrain rises into the Slate Mountains and Prieta Peak, where the industrial history of the region is evidenced by the Old Mammoth Mine and Boomerang Mine. These mineral interests are connected by a network of Bureau of Indian Affairs routes like Bia-15 and Bia-42. The boundary between Pinal and Pima counties runs across the southern portion of the sheet, cutting through the open Santa Rosa Valley where the desert floor gives way to prominent landmarks like Jackrabbit House and the high elevation of Tat Momoli Pass.
