2021 Map of Kielberg Canyon

About this map

The San Pedro River corridor defines the southwestern corner of this Arizona landscape, marking a low-lying boundary before the terrain rises sharply into the high ridges of the Coronado National Forest. This 2021 topographic survey captures a complex system of drainage and relief where the Galiuro Mountains dominate the eastern half of the quadrangle. A series of deep incisions, including Kielberg Canyon and Gardner Canyon, track the westward flow of water toward the river valley. The map documents sparse but critical water management features in this arid environment, such as YLE Tank and the uniquely named Charlie Dike. While modern infrastructure is limited primarily to Whitlock RD and N San Pedro River Rd, the detailed contouring reveals the intricate network of washes like Peters Wash and Cienega Wash that shape the local geography.
