About this map

Twentymile Hill rises above the high desert floor in this 2014 survey of Navajo County, which captures a landscape defined by seasonal water management and rugged drainage systems. The terrain is marked by an extensive network of ranching infrastructure, primarily "tanks" used to collect runoff, such as Red Hill Tank, Sixteenmile Tank, and Coyote Tank. These vital water sources support life across the arid flats between the deeper incisions of the earth.

Chevelon Canyon cuts through the eastern portion of the map, where the winding course of Chevelon Cr provides a stark topographic contrast to the surrounding plateau. Named ranch roads like Thunder Rd, Stallion Rd, and Lasso Rd crisscross the townships, following the natural contours near features like Red Hill and Wildcat Wash. The presence of Az-99 provides the primary north-south corridor through this sparsely settled region, connecting the scattered watering points and geographic landmarks.
