About this map

Montano Ranch and Rancho Seco anchor this landscape of the Sonoran Desert in Pima County, defined by a network of seasonal watercourses and livestock infrastructure. The drainage patterns are dominated by Bolas Blancas Wash and Arroyo Seco, which channel runoff through the arid terrain toward Sopori Wash in the south. The topography is punctuated by volcanic remnants and mineral-rich heights like Silver Hill and the Cerro Colorado Mountains.

Strategic water management is evident through numerous named catchments such as Burro Tank, Placer Tank, and Cradle Tank, reflecting the essential nature of water in this ranching environment. Transportation in the area relies on a few critical corridors, including Rancho Seco Rd and W Arivaca Rd, which connect these isolated homesteads and grazing lands. The map details a transition from the elevated peaks of Cerro Colorado down to the broad, sandy reaches of Las Guijas Wash.
