Light rain and snow this weekend over Colorado’s high country wasn’t enough to extinguish a wildfire burning in Rocky Mountain National Park, but it did help firefighters get a handle on the blaze, KUNC Radio, Greeley, Colo., reported.

The Fern Lake fire now covers 673 acres and is 30% contained. The fire has been burning since Oct. 9 about three miles west of Estes Park. The Moraine Park Campground is closed due to the fire.

The blaze is burning in rugged terrain with large areas of beetle-killed trees.

No structures are threatened at this time. There are 98 people currently assigned to the Fern Lake Fire. A National Incident Management Organization (NIMO) Team took over command Friday. The Coloradoan reports some personnel are being released as containment grows.

Investigators with the National Park Service are seeking information about how the fire started. Anyone with information is asked to call (970) 586-1399.
