ESTES PARK, Colo. -
A wildfire burning on the east side of Rocky Mountain National Park has grown approximately 260 acres since Wednesday.
The 660 acre Fern Lake Fire was uncontained as of noon Thursday, according to the National Park Service.
The NPS said the fire is burning in in steep, rugged terrain that includes beetle-killed trees. Although firefighters are equipped with seven fire engines, they are unable to make a direct attack on the ground.
Two heavy helitankers are working to contain the fire within park boundaries north of Glacier Creek, west of Hollowell Park and south of Trail Ridge Road.
Bear Lake Road, Upper Beaver Meadows Road and Moraine Park Campground are closed because of this fire. The NPS also said that park trails accessed from Bear Lake Road and Highway 66 are closed, as are trails south of Trail Ridge Road including the Ute Trail.
Weather Friday includes a chance of precipitation.
