About this map

The high desert terrain of the Tumacacori Mountains and Coronado National Forest dominates this landscape, defined by a critical network of water improvements. Cattle ranching and land management are evident through numerous named water sources like Mayza Tank, Lower Sardina Well, and Amole Tank. The rugged relief is punctuated by Murphy Peak and Dicks Peak, while the southwestern corner features the prominent Arivaca Lake.

Evidence of historical activity is found at a solitary Prospect near Bear Grass Tank, suggesting the mineral exploration common to this region. The map also delineates the Pima Co Santa Cruz Co line as it cuts through deep drainages such as Sardina Canyon and Lobo Canyon, providing a clear record of administrative boundaries and physical landmarks like Red Spring Pass before modern development altered the remote character of these borderlands.
