Post Fire (IDNCF)

Wildfire Status:

The Post Fire, which ignited on June 10, 2025, is currently active and has affected an area of 144 acres. The fire has spread rapidly due to weather and fuel conditions that are atypical for this time of year, compounded by the rugged terrain which presents challenges for evacuation and firefighting operations. As of the latest updates, approximately 94% of the perimeter has been contained, while smoldering remains evident in individual stumps and downed logs within the established boundaries. The primary concern remains the potential for fire roll-out in steep areas, which could threaten critical infrastructure and resources in the Highway 12 corridor between Lolo, Montana, and Kooskia, Idaho.

Fire management has transitioned from the Northern Rockies Complex Incident Management Team 5, led by Incident Commander Joe Sampson, to a local Type 4 organization. The response strategy employed is full suppression, focusing on confinement, containment, and point protection of vulnerable areas. Currently, there are no fire restrictions, nor are there any road, trail, or area closures in effect. A total of 29 personnel are actively engaged in firefighting efforts, and the cause of the fire is still under investigation.

Weather conditions and the nature of the fuels involved—primarily timber with grass and understory—have played a significant role in the fire's behavior. Fire response teams are closely monitoring the situation to mitigate risks, particularly in areas where steep terrain could exacerbate the fire's spread. The situation remains dynamic, and updates will continue to be provided as the incident evolves.
