The Post Fire started on Tuesday, June 10 and weather and fuel conditions caused more rapid spread than is typical for this time of year. The fire is burning in rugged terrain with long evacuation times should an accident occur. This is a consideration when determining firefighting strategies and tactics.

The greatest potential impacts are to the Highway 12 corridor that runs between Lolo, Montana and Kooskia, Idaho. It also has the potential to impact various forest infrastructure, recreation sites, and natural and cultural resources. 

Management of the fire transitioned to the Northern Rockies Complex Incident Management Team 5 (IC Joe Sampson) on June 14 at 6:00 a.m.

The fire is being managed under a full suppression strategy, implementing strategies of confinement, containment, and point protection. Currently there are no fire restrictions or road, trail, and area closures.
