Crater Range dominate the northern landscape of this 2014 survey, where the arid terrain of Maricopa and Pima counties converges. The topography is defined by the steep elevation changes of these peaks, which give way to the broad alluvial plains of Childs Valley and the prominent rise of Childs Mountain to the south. This region is a study in desert hydrology, with the intricate drainage patterns of Midway Wash and the extensive network of Tenmile Wash carving paths across the basin floor. Transportation in this section of the Sonoran Desert is anchored by Az-85, which runs along the eastern edge of the quadrangle. The map captures the remote character of the borderlands between the two counties, documenting the complex system of sections and townships that organize this largely undeveloped wilderness.
