The Bridger Teton Avalanche Center is warning that snow on some of the mountain slopes is naturally releasing now, making for potentially dangerous travel in the back country. Naturally released loose snow sloughs were observed in steep couloirs in Grand Teton National Park early this week. The sloughs were small but running fast on hard old snow surfaces.
Under current conditions, loose snow sloughs and pockets of wind slab could be human triggered in steep terrain at the mid and upper elevations and could be dangerous. These types and sizes of avalanches are much less threatening in lower angle terrain that is open and free of obstacles and terrain traps, but should still be considered.
