A 2-acre grass fire in southwest Teller County has been contained, said agency spokesman Marc Porcelli.

The county activated its wildfire task force near mid-day and controlled the blaze, which began near the intersection of County Road 12 and Highway 121.

"They were able to get there real quick and get a line around it and right now it is contained and getting cleaned up," Porcelli said.

Officials didn't take any chances, triggering a reverse 911 call for some residents in the area, but Porcelli said the fire never really threatened residences. The department still is investigating how the fire started.

By Wednesday afternoon a small fire west of La Veta was 40 percent contained. The Klickus fire was reported by the Huerfano County sheriff. Like other fires around the state, the Klickus fire was fanned by high winds. It forced the evacuation of three homes.

The Denver Post reported that a fire in Rocky Mountain National Park grew from about three acres Tuesday morning to as many 400. The fire was burning in trees killed by mountain pine beetles are feeding the Big Meadows fire on the west side of the park.

The fire is about 4.5 miles from the Green Mountain Trailhead in a remote area of the park west of the Continental Divide, and is moving to the northeast toward Nakai Peak.

Authorities believe the fire was started by lightning.
