The San Pedro River serves as the primary artery through this high-desert landscape in Cochise County, anchoring a network of irrigation works essential to the local valley economy. The Pomerene Canal and Saint David Ditch flank the river, tracing the contours of the San Pedro Valley to support agricultural life in settlements like St. David and Curtiss. These features illustrate the enduring reliance on gravity-fed water systems in a region defined by its arid climate.
