About this map

The southern end of Picacho Peak State Park dominates the northern edge of this desert landscape, where the Santa Cruz River and Greene Canal cut through the arid terrain. The map captures a significant concentration of historical remnants centered around the former townsite of Sasco, evidenced by the Sasco Ruins and the nearby Sasco Cem. These features, alongside the Old Railroad Grade, suggest a period of industrial or mining activity that has since transitioned to a quieter ranching and conservation era.

South of the river, the topographic relief increases sharply as the Samaniego Hills rise, including prominent summits like Cerro Prieto and Pan Quemado. Local water management is visible through numerous wells and tanks, such as Sasco Tank, supporting operations like the La Osa Ranch. The boundary between Pinal and Pima Counties runs through the southern portion of the sheet, dividing this complex mix of natural desert peaks and historical ruins.
