Fire in historic Bear Gulch Tunnel triggers trail closures

The Caribou-Targhee National Forest has issued an immediate emergency closure for a section of the Railroad Grade Trail following a fire inside the historic Bear Gulch railroad tunnel.

"A lack of structural stability within the Bear Gulch Railroad tunnel has prevented firefighters from accessing internal heat sources that continue to produce smoke that may be visible in the Bear Gulch Area," stated the Forest Service in a release.
