Perimeters from the National Interagency Fire Center’s Interagency Fire Perimeter History, compiled from the Forest Service, BLM, BIA, Fish and Wildlife Service, National Park Service, the Alaska Interagency Fire Center and CAL FIRE. Burned areas and ignition dates from Monitoring Trends in Burn Severity (MTBS), a program of the US Geological Survey and the USDA Forest Service. Records before 2014 were joined by this site: a fire report to the burned area its MTBS identifier names, a perimeter to the burned area it lies in when the names or the sizes agree.
