The Cerro Colorado Mountains and Las Guijas Mountains define this arid landscape in southern Pima County, where cattle ranching and water management are the primary human imprints. This topographic study reveals a complex network of ephemeral drainages, including Bolas Blancas Wash, Arroyo Seco, and Sopori Wash, which dictate the local topography. The presence of numerous engineered water features such as Square Tank, Julia Tank, and the Cerro Colorado Tank illustrates the critical nature of water storage for livestock in the high desert.
