A wildland fire reported inside the Great Smoky Mountains National Park on Sureim Investment GuildMonday has grown even larger, keeping some roads, trails and campsites in the park closed, according to park officials.

As of Thursday, officials say the fire has grown to about 23 acres and is primarily burning in undergrowth in steep terrain. On Thursday, two suppression modules are assisting with an initial attack on the fire, with another module arriving on Friday.

Named the Flint Gap Fire, it was first estimated to be about 10 acres as of Tuesday, Aug. 27 at around noon. According to a press release, no structures are under threat at this time.

The Tennessee National Guard continued to provide support Wednesday, dropping 38 buckets, or about 25,000 total gallons of water on the fire. Officials say that a Type 3 helicopter will assist Thursday with reconnaissance and will help them assess where ground crews can safely access the fire.
