If you're wondering why the Smokies are filled with smoke a 744-acre controlled burn is taking place in Monroe County in the Cherokee National Forest.

The smoke caught a lot of people off guard, and it doesn't appear the controlled burn was well-announced to the public ahead of time.

The U.S. Forest Service scanned a document with details about the burn on May 23 to its archive, however the release itself was not readily found on the Cherokee National Forest notices website or social media.

According to the release, the burn will occur from May 28 to June 1 in Monroe County approximately six miles from the Indian Boundary Campground and 1 mile north of the Jake Best Campground.
