2021 Map of Samaniego Hills

About this map

The southern end of the Pinal County line meets Pima County amidst the arid lowlands and prominent peaks of the Samaniego Hills. This landscape is defined by the ephemeral passage of the Santa Cruz River and the engineered water management of the Greene Canal, which cuts across the northern desert floor. Historical traces of early twentieth-century activity are centered near the Sasco Cem, a remnant of the mining and smelting hub that once operated in the area. Travel through this region relies on a network of rural routes such as S La Osa Ranch RD and E Sasco RD, which navigate around significant elevations like Cerro Prieto and Pan Quemado. The map details a transition from the agricultural canal system in the north to the rugged volcanic formations and drainage patterns of Los Robles Wash in the south.
