Firefighters are battling a 25-acre wildfire along the northwest boundary of Great Smoky Mountains National Park on the Happy Valley Ridge.
The fire north of the Abrams Creek Campground was reported about 6:45 p.m. on Wednesday. It was still burning Thursday night.
A park spokesperson said the fire is spreading slowly with flame lengths less than three feet high through a pine-oak forest. At times, the flames have been as high as five to six feet during the hottest, driest parts of the day.
Firefighters from the park and the Tennessee Division of Forestry responded to the fire. A 10-person Hotshot fire crew from Cherokee National Forest are expected to assist with fire suppression efforts Friday morning.
The fire is currently not threatening any structures, roads or trails, and all park areas remain open at this time, the spokesperson said.
Park visitors can expect to see smoke from the Foothills Parkway West and the Abrams Creek area of the park.
The cause of the fire is unknown, but it is possible it was started by lightening, the spokesperson said.
