- Note on the perimeter
- Fire perimeter modified using Landsat Image Service. Image IDs: LC08_L2SP_073014_20130614_20200912_02_T1 and LE07_L2SP_073014_20120619_20200909_02_T1.
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.

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.
