GNFAC Avalanche Advisory for Fri Mar 14, 2014
Snowpack and Avalanche Discussion
Bridger Range Gallatin Range Madison Range
Lionhead area near West Yellowstone Cooke City
This natural avalanche was spotted on an ESE aspect on Alex Lowe Peak in Hyalite. Other simiilar slides were seen in the area. Photo: B. Vandenbos
SE aspect at about 9200 feet in the Taylor Fork area of the Southern Madison Range. Weak layers are evident in this photo and they were easily found when digging this snowpack. We found a very thin layer of facets above an ice crust about 1.5 feet deep. This layer formed more recently and shouldn't last too long, nor does it exist on many slopes. A bigger issue are the December facets near the ground. We were surprised how easily these broke in stability tests (profile). Photo: GNFAC

7 riders in the Jefferson's, all wearing beacons and airbags, climbing one at a time on what they considered a small angled slope triggered a pretty deep slide and guy rode it out, ended up on his sled when it stopped. No injuries and no one buried. Photo: J. Watt
