PIGEON FORGE, Tenn.  — A wildfire burning in a resort area outside the Great Smoky Mountains National Park in eastern Tennessee has damaged or destroyed nearly 60 large rental cabins and is threatening additional homes.

The 145-acre fire was first reported around 5 p.m. EDT Sunday in Sevier County, said Ben Bryson, a fire resources coordinator with the Tennessee Division of Forestry. National Guard helicopters were pouring water on the fire.

Although the fire was initially contained Monday morning, officials with the Tennessee Emergency Management Agency reported in the afternoon that the fire breached the containment and was threatening an additional 15 to 20 homes.

Some of the cabins were occupied and about 150 to 200 people were evacuated, but Byson said no injuries were reported.
