The three sizes are three measurements: the size the agency reported when the fire was out, the burned area MTBS drew from satellite imagery before and after, and the GIS area inside the final perimeter, unburned islands included. They rarely agree exactly.

Burned areas and ignition dates from Monitoring Trends in Burn Severity (MTBS), a program of the US Geological Survey and the USDA Forest Service.
