- Note on the perimeter
- Fire reported by FS Beaver near Cavity Lk @ .5 ac. When IC arrived, fire near 100 acres. Aerial attack by 2 CL-215's & 1 CL-415 & T2 Helo. Transitioned to Type 3 on 07/15/06 @0700.
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.
