Fires in the Granite Pass Complex are being managed under a full suppression strategy with public and firefighter safety as the number one priority. The Granite Pass Complex consists of four fires. The Shotgun and Boulder Creek fires are on the Nez Perce-Clearwater National Forests. The BM Hill Fire is on both the Nez Perce-Clearwater and the Lolo National Forests. The Lolo Creek fire is exclusively on the Lolo National Forest. Since Tuesday evening, the fire area received .25-.30 inches of rain. Cooler temperatures and higher relative humidity levels allowed crews to shift to repair work on lines and roadways.

Lolo and Nez Perce-Clearwater National Forests

BM Hill Fire: 5,006 acres, located approximately 1.25 miles north of the Lolo Pass Visitor Center and one-half mile west of Highway 12. Repair work is underway in several areas around the fire including chipping to remove woody debris, line repair, and road grading. Engine crews will continue to patrol and monitor for areas of isolated heat. Heavy equipment will be moving along Highway 12 and Fish Creek Road, please slow down and exercise caution as you are driving through the area.

Lolo National Forest

Lolo Creek Fire: 165 acres, located approximately one quarter mile west of Highway 12 and one mile north of the Lolo Pass Visitor Center. Crews have completed control lines on the fire perimeter and the fire is in patrol status.

Nez Perce-Clearwater National Forests

Shotgun: 528 acres, located approximately two miles south of the Lolo Pass Visitor Center and four miles west of Highway 12. Boulder Creek Fire: 211 acres, located approximately five miles west of the Lolo Pass Visitor Center. The Shotgun and Boulder Creek fires are in very remote, steep, and rugged terrain. Fire spread has been minimal due to the 2015 Boulder Fire scar where limited fuels are available.


Cooler than average temperatures with precipitation diminished fire activity since Tuesday. On Thursday, the high temperature is forecast to be 61-66 with relative humidity at 50-55%. Isolated rain showers are possible Friday evening with a short-term warming and drying trend to follow.
