"AvalancheTeton Pass, or Highway 22, is closed in both directions until further notice, after an artificially triggered avalanche in Glory Bowl buried the highway under a huge debris pile. Crews are actively working to clear the debris, but the road may not reopen until Tuesday afternoon or later, according to WYDOT. Recent, heavy snowfall and high winds in the Tetons has rapidly raised the avalanche danger, leading to several large slides."
"The Wyoming Department of Transportation operates a Gazex tube in the Glory Bowl slide path for avalanche mitigation. Gazex tubes use compressed gas to create explosions in avalanche starting zones, triggering avalanches artificially. At the time of the recent slide, the road was closed for avalanche mitigation. Estimated time of reopening is Tuesday afternoon, December 23. Teton Pass is a key connector between Jackson Hole and communities in eastern Idaho, rising to more than 8,400 feet and cutting directly beneath several large avalanche paths."
Teton Pass (Highway 22) is closed in both directions after an artificially triggered avalanche in Glory Bowl buried the highway under a large debris pile. Crews are actively clearing the debris, and WYDOT estimates reopening may occur Tuesday afternoon, December 23. Recent heavy snowfall and high winds rapidly elevated avalanche danger across the Tetons, producing several large slides including a four-foot crown release on Rendezvous Mountain and a nearly three-foot, 1,500-foot-wide slide on Mount Glory. WYDOT uses a Gazex tube in Glory Bowl for mitigation, and the road was closed for triggered-control operations when the slide occurred. Travelers are urged to plan alternate routes, monitor WYDOT updates, and prepare for ongoing winter impacts.
