The Roaring Lion fire in the Bitterroot National Forest outside of Hamilton, Montana has destroyed several structures, although officials have yet to confirm how many, according to posts on InciWeb.
Five hundred homes remain under evacuation notice, and on Monday the fire had burned more than 3,000 acres.
Crews made some gains establishing a fireline on Sunday night, and were aided by 5 helicopters on Monday, according to InciWeb:
Last night, dozer and hand crews were able to punch in containment lines in a good portion of the East side of the fire. They were also able to put out multiple spot fires around residences.
The Type 1 team is expected to take over operations on Tuesday. The cause of the fire remains unknown.

Fanned by hot winds, the Roaring fire exploded in a massive plume of smoke on Sunday. Visit InciWeb to see more photos of the fire. Also, check out this time-lapse video of the fire (note: it will take about 20 seconds for images of the fire to start).
