The Great Basin Incident Management Team 4 says the Millie Fire, burning 20 miles south of Bozeman, is now 10 percent contained.
Fire crews briefed the public during a meeting on Monday evening, and say the 10,186-acre blaze is slowing down.
In some areas, it's reaching rocky cliffs and running out of fuel.
Plus, fire fighters are making progress where it's active.
Crews constructed containment lines on the west flank, south side and northern edge. And, they chipped along the road in Hyalite Canyon to get rid of fuel.
Officials say more crews continue to arrive to provide help, including two Type 2 crews from Pennsylvania that hit the ground on Sunday.
The Forest Service told residents they're putting together a plan of action for rehabilitating damaged land.
"As fire progresses and some of the fire line begins to be cold and contained and safe- we start thinking about what we're going to do to reclaim that" said Lisa Stoeffler, with the Gallatin National Forest.
She said they'll work "to bring back in the vegetation and duff, and keep those fire lines from becoming erosion hazards."
They'll look at erosion control, water diversion, weeding, seeding and making roads and trails safe.
Stoeffler said they plan to start work in several days, in areas where the fire is completely out and the area 100 percent safe. From there, they'll follow the fire suppression line.
Officials say a total of 412 people are assigned to the Millie Fire. Two Type 1 hand crews, seven Type 2 hand crews, 21 engines, and eight dozers are actively working the blaze.
Three helicopters are making water drops on the headwaters of South Cottonwood Creek. Crews are working to protect structures in South Cottonwood Canyon, Hyalite Canyon and the Blanchard area.
