ROCKY MOUNTAIN NATIONAL PARK, Colo. -

A wildfire burning on the east side of Rocky Mountain National Park has prompted evacuations of a nearby campground, along with backcountry campsites and trails in the area.
 
No structures are threatened.
 
The fire has burned across about 300 acres and is about 2 miles west of the Fern Lake trailhead. Park officials say the blaze was burning to the north in steep, forested terrain.
 
Cloudy, turbulent conditions kept a single-engine air tanker and helicopter from fighting the flames from above Tuesday. Crews planned to monitor the flames overnight.
 
In southwest Colorado, crews were trying to contain a 110-acre Goblin Fire that federal officials say may have been started by the Durango & Silverton Narrow Gauge Railroad Train.
 
On Monday, firefighters near Red Cliff had to extinguish two abandoned campfires.
