MISSOULA, Mont. -

Fire crews took advantage of higher humidity and lower fire activity when fighting the flames on the Lolo Creek Complex fire on Friday.  Crews concentrated on building lines in the Sawmill Gulch area, working to build line up to the northeast corner. Hotshot crews, dozers and engines also worked to hold an eastern flank.

Crews also focused on the Woodman Gulch area, where there’s a really steep draw with fire at the bottom. Fire officials say it will prove to be difficult to put firefighters on the ground in the area when activity picks up.

Containment rests at 40 percent and acres burned are reported at 9,962. Five residences have been confirmed destroyed, and roughly 1,200 residences remain threatened.

Crews plan to continue aggressive suppression efforts, focusing on the blaze west of Sleeman Gulch and north of Highway 12. Residences remain evacuated from Sleeman Gulch to Graves Creek Road, and Highway 12 remains closed.
