The San Pedro River corridor defines the eastern edge of this landscape, carving through the high desert of the Pinal and Pima County border. This 2018 survey illustrates a complex network of seasonal drainages, including the prominent Peppersauce Wash and the southern reaches of Catalina Wash, which feed into the river basin. The terrain rises sharply toward the Little Black Hills and the deep incisions of Alder Canyon, reflecting the topographical transition from the valley floor to the surrounding highlands.
