About this map

Trinity Mtn rises as the central landmark of this Coconino County landscape, where the seasonal drainage of Chino Wash snakes through the high desert terrain. This 1981 survey documents a remote ranching and resource landscape defined by its critical water infrastructure, featuring a dense network of catchment basins such as Horseshoe Tank, McCracken Tank, and Trinity Tank. The reliance on these tanks highlights the arid nature of the region, where every named water source served as a vital node for local land use.

Industrial activity is evident in the southwestern portion of the quadrangle, where several Quarries and a Quarry Tank suggest local stone extraction. Other utilitarian features include a Borrow Pit and a Pipeline cutting across the southern reaches. The map's detail, including the distinct naming of Chino Tank and Cinder Tank, provides a precise record of the features that sustained movement and industry in this part of Arizona during the late twentieth century.
