About this map

Twentymile Hill rises above a high desert landscape defined by essential water management in this northern Arizona survey. The terrain is marked by an extensive network of ranching infrastructure, where named reservoirs such as Coyote Tank, Cement Tank, and Sixteenmile Tank provided vital resources for livestock. Drainage patterns are dominated by Chevelon Creek and Clear Creek, which cut through the arid plains toward the Little Colorado River basin.

A grid of rural routes, including Thunder Rd, Pinto Rd, and Lasso Rd, suggests the parceling and management of this open range in the early 21st century. Distinctive elevations like Red Hill and its associated Red Hill Tank serve as primary landmarks for navigation across the plateau. The presence of Potato Wash in the southeast corner further illustrates the intermittent watercourses that characterize this high-elevation region of Navajo County.
