- Note on the perimeter
- Fire perimeter modified using Landsat Image Service. Image ID: LC08_L2SP_076015_20130619_20200912_02_T1 and LE07_L2SP_076015_20110708_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.
