2021 Map of Additional Hill

About this map

Coconino Rim cuts through this high-desert landscape in northern Arizona, marking a significant topographic break within the Kaibab National Forest. The region is defined by its arid drainage systems, including the seasonally active Needmore Wash, Lava Wash, and Cedar Wash. This survey documents a remote section of the San Francisco Volcanic Field, where the reliance on scattered water catchments is evident through numerous named sites such as Malpais Tank, Michelbach Tank, and Eugene Gordy Tank. These tanks and the presence of BLM RD 6191 indicate a landscape primarily used for ranching and resource management. The map also includes the northern descent of Lockwood Canyon and the prominent height of Additional Hill in the northeast, providing a clear record of the intersection between forest boundaries and geological formations.
