FEATHERVILLE, Idaho (KBOI) - Trinity is holding its own.

Boise National Forest spokesman Dave Olson told KBOI-TV Thursday morning that the Trinity Fire near Featherville is about two miles from the town.

Fire crews started the back burn late Wednesday using "ping pong ball" incendiary devices dropped from helicopters.

The burnout area is directly behind properties in Featherville starting north of the town, and a fireline has been set up just yards behind the town.

Olson said he believes the burnout has been successful so far, creating a buffer between the burnout fire and the main fire.

Fire crews plan today to continue working the fire starting on the westside and working south.

The largest obstacle, Olson says, is smoke inversion that creates unsafe flying conditions. He thinks the smoke should lift by mid-afternoon, allowing more aerial drops.

Officials said a meeting will be held at 10:30 a.m. in nearby Pine.
