This afternoon, an avalanche was triggered by a snowboarder in Glory Bowl, a very popular backcountry ski run on Targhee Pass. At the mid and upper elevations soft slabs up to 3 feet in depth lie upon weak layers and a slick October crust. Yesterday afternoon the southeast face of Mt. Hunt in Grand Teton National Park released naturally and ran full track. At the mid elevations soft slabs were triggered on approach by skiers.
Similar events are likely to be human triggered today.
Avalanches are unlikley at the lower elevations. Jim Whalen said. Friends reported him missing after finding tracks that disappeared in the slide. It wasn't known whether he triggered the slide that covered some 40 feet of Wyoming Highway 22, Whalen said. The highway connects the Jackson Hole region with the Idaho side of the Teton Range.
