2021 Map of Esperanza Mill
USGS Topo · Published 2021About this map
The industrial and desert landscape south of Green Valley is defined by the ephemeral watercourses that drain the high ground toward the Santa Cruz River. At the heart of this terrain lies the Esperanza Mill, a focal point for the regional mineral processing industry. The map illustrates a complex network of arroyos, including Amargosa Wash, Escondido Wash, and Demetrie Wash, which carve through the arid flats. Man-made water catchments like Duval Lake, Ball Tank, and Salcedo Tank dot the landscape, indicating the critical importance of water management for both industry and ranching in this Pima County corridor.
