Nineteen firefighters with the elite Granite Mountain Hotshots crew lost their lives on June 30, 2013, when flames from the fast- moving Yarnell Fire trapped them in a canyon. The Granite Mountain Interagency Hotshot Crew was a crew within the Prescott Fire Department whose mission was to fight wildfires and when not doing so, engaged in work to reduce growth of fire-prone vegetation. Originally founded in 2001 as a fuels mitigation crew, they were later formed into Crew 7, a Type II IA hand-crew in 2004, and eventually transitioned into a Type I Inter-agency hotshot crew in 2008, 19 of the 20 members of the group perished fighting the Yarnell Hill Fire. The Yarnell Hill Fire was the deadliest wildland fire since the 1933 Griffith Park Fire in Los Angeles.
