The forest maintains a full-time fire staff throughout the summer, not only to control and extinguish fires that pose threats to people and structures but also to set controlled burns. Their jobs include maintaining a high level of preparedness, keeping a vigilant lookout for fire activity, responding to reports of fires, maintaining equipment, monitoring weather and relative atmospheric dryness, and preparing daily fire activity reports, which are used to post fire information for visitors and staff. The forest has wildland fire engines, pumps, hand tools and fire hose at its disposal. A helicopter can be summoned quickly, along with support from the South Central Idaho Interagency Dispatch Center, including a team of smokejumpers and air tankers used to provide air support in dropping flame retardant and water. There are small areas around Stanley and Mount Harrison where aerial retardant would not be used in the case of a fire. The 10-member Sawtooth Helitack crew was established in 1963 and is based at Friedman Memorial Airport in Hailey. In the case of larger fires, the National Interagency Fire Command can quickly mobilize available resources. Only four of the original fire lookout towers remain standing in the forest, but they are no longer in use: Iron Mountain, Horton Peak, Lookout Mountain, and Mount Harrison, which was last fully staffed in 2007. Many of these towers were built by the Civilian Conservation Corps during the Great Depression.:
