Sunday, firefighters continued to secure the fire line and mop up hot-spots in what forest officials have dubbed the 392 Fire.

The fire sparked in Park County, which is about 9.5 miles northeast of Como, around 12:40 p.m. on Saturday.

The now 90-acre fire is reportedly 50 percent contained and was started by human activity, according to the U.S. Forest Service. It is threatening one structure at this time - a ranch in Park County.

Officials say the fire is being fueled by dry grass in the area and being pushed on by winds.

Campers from County Road 39 and F.S. 129 were evacuated on Saturday for their safety.

County Road 56 at 285 is now open and the portion of County Road 39 that was closed will likely open Monday.

No injuries have been reported at this time. Stay with 9NEWS for updates on this wildfire.
