About this map

The northern reaches of the Kaibab National Forest dominate this high-desert landscape in Coconino County, characterized by the dramatic topography of the Coconino Rim. This 2018 survey reveals a terrain defined by complex drainage systems and isolated water catchments, crucial for ranching and wildlife in this arid region. Major ephemeral watercourses including Lava Wash, Needmore Wash, and Cedar Wash carve through the land, descending from elevations near Additional Hill.

Evidence of historical and contemporary land management is found in the network of livestock tanks bearing family or descriptive names, such as Michelbach Tank, Eugene Gourd Tank, and O'Dell Tank. Access to this remote area is facilitated by unimproved routes like Crazy Hill Rd and BLM RD 6191. The transition from the high plateau of the rim into the depths of Lockwood Canyon illustrates the stark geological shifts typical of the Colorado Plateau's western margins.
