Authorities say a fire at Pilot Mountain State Park that’s burned 800 acres was about 70% contained on Sunday (Nov. 11), WGHP-TV, High Point, N.C., reported.

State Parks and Recreation spokesman Charlie Peek said Sunday that about 70 firefighters are working to extinguish the blaze, which began as a prescribed burn and was only supposed to reach 180 acres.

Peek says the fire has a low intensity and is burning dead wood, leaves and undergrowth with little damage to standing trees.

He says that means this blaze is reducing the risk of a catastrophic fire in the future.

State officials closed the park after flames jumped the fire line Thursday.

No one has been injured. Damage to park facilities is limited to fence rails and posts at viewing areas.
