Steamboat Springs Nearly 200 firefighting personnel are working to get the upper hand on the Wolf Fire, which had grown to more than 6,100 acres by Sunday evening, according to a news release from the Northwest Colorado Fire Management Unit.
Fire officials reported Sunday that the wildfire was 40 percent contained and that they expected full containment by Friday.
Two air tankers are dropping retardant, and a helicopter is dropping water in areas that are difficult for firefighters to reach, according to the release.
The wildfire, which is about five miles south of Elk Springs in western Moffat County, was sparked Friday by lightning on Bureau of Land Management land and since has moved onto private land. It is burning in sagebrush and pinion and juniper trees, and rough terrain has made the burn area difficult to navigate for firefighters, according to the release.
A smaller fire in Moffat County, the Divide Fire, grew to an estimated 408 acres by Sunday evening and is 100 percent contained, according to the release. The Divide Fire is about five miles south of the Wolf Fire on BLM land. Lightning also has been determined as the cause of the Divide Fire.
No structures are threatened by either wildfire, according to the release.
