1972 Map of Kielberg Canyon

About this map

The Galiuro Mountains dominate this high-desert landscape in southeastern Arizona, where the remote canyons and ridges are preserved within the Coronado National Forest and the Galiuro Wilderness. Human presence is defined by historic water management and ranching infrastructure, such as the YLE Ranch, numerous corrals, and the YLE Tank. The map tracks the vital drainage systems of Kielberg Canyon, Peters Wash, and Cienega Wash, which eventually feed toward the San Pedro River in the southwestern corner. For those interested in regional industry and mineral history, the 16 to 1 Mine is situated along the steep eastern slopes. The survey also carefully delineates the county intersections of Graham, Pinal, and Pima, providing a clear view of how these political boundaries cross the canyon lands.
