2018 Map of Telegraph Wash

About this map

The Santa Teresa Mountains dominate the western edge of this desert landscape, where steep topography transitions into the drainage systems of the Gila River valley. The hydrology of this Graham County region is defined by ephemeral courses like Black Rock Wash and Telegraph Wash, which carve through the arid terrain. Such drainages are vital features in this high-desert environment, evidenced by the scattered water improvements like V L Tank and Middle Point Tank that supported cattle ranching operations. Significant geological relief is found in Dark Canyon and Fourmile Canyon, providing a detailed look at the rugged eastern slopes of the mountain range. This 2018 survey also tracks the local road network, including W Klondyke Rd and Co Rd 30, which provide access to these remote areas.
