About this map

Mining operations and remote ranchlands define the border country of the Coronado National Forest during the late 1970s. The landscape is marked by numerous extraction sites tucked into the deep drainages of Cobre Ridge and Canyon del Oro Blanco, including the prominent Yellow Jacket Mine, Austerlitz Mine, and the curiously named Saint Christopher Mine. The presence of ruins at Old Glory and Casa Piedra suggests a long history of human occupation in these isolated canyons near the international line.

Water management is critical in this arid terrain, as evidenced by a dense network of specialized improvements like Aqua Cercada Tank, Road Canyon Well, and Sierra Well. These features supported isolated holdings such as Oro Blanco Ranch and Tres Bellotas Ranch. This survey captures the region just before the early 1980s, preserving a record of the intricate jeep trails and spring-fed camps that sustained cattle and mineral interests along the Arizona Sonora boundary.
