San Xavier del Bac Mission stands as a prominent cultural landmark in the northeastern portion of this 1990s survey, situated within the Santa Cruz Valley. The landscape is defined by the extensive San Xavier Indian Reservation, which encompasses a mix of traditional land use and significant industrial activity. Major terrain features like Black Mountain and Twin Buttes dominate the central topography, while the southern reaches show heavy modification from resource extraction, characterized by a large Quarry, a Mine Dump, and extensive Tailings piles. Transportation through the reservation is facilitated by Mission Road and the Twin Buttes Road, alongside the industrial utility of the Pima Spur railroad line. Traces of historical land tenure appear in the Rancho de Martinez boundary, while modern utility is represented by a Powder Magazine and a network of pipelines and wells.
