From the Gallatin Avalanche Center in Montana this morning:
Snowpack and Avalanche Discussion
Southern Madison Southern Gallatin Lionhead Range
"A snowmobiler from Idaho Falls is missing and presumed dead near Reas Peak in the Centennial Range south of West Yellowstone. His snowmobile was found partially buried in avalanche debris but he is unaccounted for. The rescue will continue today. Read a short clip from the East Idaho News here. We will update this post as more information becomes available.
Although the Centennial Range is out of our forecast area, it has a similar snowpack structure to the Lionhead area and mountains around West Yellowstone. The southern mountains have received a heavy amount of snow over the past 36 hours and the snowpack remains under a tremendous amount of stress. Facets buried 2-4’ deep are the primary concern and slides failing on this layer will be large and dangerous (video, photo, photo). It will be possible to trigger entire slopes from the bottom or from a distance and travel in avalanche terrain is not recommend.
As more snow and wind impact the area today, very dangerous avalanched conditions exist. Natural and human triggered avalanches will be likely on wind loaded slopes which have a HIGH avalanche danger. Human triggered avalanches are likely on non-wind loaded slopes which have a CONSIDERABLE avalanche danger."
One of us is missing this morning. A prayer for him. Continuing efforts for a recovery are reportedly ongoing. Stay safe Fremont County SAR and all else currently involved.
Anybody with facts could report here and let us know.
Gods speed...
