About this map

Coronado National Forest dominates this topographic study of the Pinaleño Mountains, characterized by dramatic elevation changes and a dense network of high-altitude trails. The terrain rises sharply from the northeastern desert washes to the prominent summits of Mt. Graham and Heliograph Peak, the latter featuring established Radio Facilities and a lookout tower. This era shows the developed recreational infrastructure of the range, with sites like Turkey Flat, Shannon Park Campground, and Arcadia Campground providing access to the cooler mountain air.

Water management in this arid environment is evident through features like Lebanon Reservoir No 1 and Spring Canyon Dam, while the complex drainage systems of Marijilda Creek and Noon Creek define the ridges and canyons. The presence of several springs, including Twilight Spring and Helldive Spring, highlights the critical natural water sources that sustained local activity. The map also records the primitive transportation network of the time, including the Round the Mountain Trail and various pack trails used for forest management and exploration.
