CCC
The Civilian Conservation Corps (CCC) completed many projects in the 1930s. "Men from all over the country came to the area to work in numerous camps, several located on Mount Graham." Treasure Park and Columbine were used during the summer months, and Arcadia, Noon Creek and other sites were used during the winter months. "Many of the improvements at campgrounds, as well as hiking trails, roads and other facilities now enjoyed by many visitors to Mount Graham, were built by the CCC personnel."
One of their projects included the construction of a 99-foot (30 m) steel framed lookout tower on Heliograph Peak to watch for fires in the Pinaleños and nearby mountain ranges including the Galiuros, Dos Cabezas, White Mountains, Gilas, Rincons and Santa Catalinas. The tower still stands as of 2006, however, most fire watching efforts in Arizona are conducted from the ground or by airplane.
