2018 Map of Avra

About this map

Saguaro National Park dominates the eastern landscape of this Pima County quadrangle, where the Tucson Mountains rise sharply above the desert floor. The map documents a striking transition from the protected wilderness of Wasson Peak and Amole Peak to the modern engineering of the Central Arizona Project Aqueduct in the west. Significant cultural and geological landmarks are identified throughout the park, including the petroglyph site at Signal Hill and the narrow passage at Contzen Pass. In the northern reach, the settlement of Marana sits near the base of Twin Peaks, while the residential expansion of Avra Valley spreads across the alluvial plains. This survey details a network of desert drainages like Picture Rocks Wash and Bajada Wash that define the hydrological character of the basin.
