Buenos Aires National Wildlife Refuge and the Coronado National Forest converge in this high-desert portion of Pima County, where the southern reaches of the Altar Valley meet rising mountain slopes. The small settlement of Puertocito sits near the head of the Puertocito Wash, a central drainage for the area's intricate system of seasonal watercourses. The landscape is defined by its water management history, evidenced by numerous named tanks such as McKay Tank, State Tank, and Old Forester Tank that support livestock and wildlife in this arid environment.
