U.S. Forest Service firefighters planned to work overnight to try to contain a fire that had burned 44 acres near Lake George in Park County by Sunday night, the Forest Service posted on its website.
Called the Puma Fire, the blaze was reported just before 5 p.m. about 6 miles west of Lake George. It was 0 percent contained as of 9 p.m.
Two 20-person hand crews were expected to relieve the night shift on Monday morning.
Smoke from the fire was visible from U.S. 24 during the much of the day when the Forest Service reported torching in trees and spotting. By nightfall, the fire had subsided, with minimal creeping in heavy timber.
A helicopter dropping water from a bucket and crews and engines from various fire and law enforcement agencies battled the fire for several hours Sunday. The helicopter was expected to resume trying to douse the blaze in the morning.
The nearest threatened structures are about a quarter-mile from the fire, the Forest Service said. Forest Service roads 250 and 250A are closed.
