The Tohono O'odham Indian Reservation dominates this desert landscape, where the Slate Mountains rise above the Santa Rosa Valley. Mining activity defines much of the eastern terrain, evidenced by numerous named operations including the Orizaba Mine, Jackrabbit Mine, and Old Mammon Mine. A network of water management features, from the Aqueduct and Pipeline to the Sewage Disposal Ponds near the boundary of Pinal and Pima Counties, reflects the infrastructure required to support settlement in this arid environment.
