from the Gallatin National Forest Avalanche Center - March 12, 2013 - this report is by Doug Chabot. This advisory Does Not Apply to operating ski areas.
This morning there is no new snow to report. Mountain temperatures are in the low teens Fahrenheit under partly cloudy skies. West winds have decreased from 20 to 40 mph to 15 to 20 mph. Clouds will build throughout the day as temperatures rise into the upper 20s Fahrenheit and winds remain the same. The southern mountains may get a few flurries later today, but accumulations should be less than an inch.
Snowpack and Avalanche Discussion:
Bridger, Gallatin, and Madison Ranges, Lionhead Area near West Yellowstone, and Cooke City:
Yesterday's strong winds scoured high elevation terrain with a few slopes getting loaded and forming stubborn wind drifts. Mark found shallow wind slabs outside Cooke City this weekend (photo) and kicked off a small 8 inch pocket yesterday. I toured north of Bridger Bowl into the Hourglass Chute on Sunday and found stable conditions, but I also avoided the smooth wind-whale of drifted snow on the northern entrance. That same day in the Bridger Range, a skier in Naya Nuki Bowl was caught in a small avalanche when he triggered a wind-loaded pocket under some cliffs (photo). Although small, these types of slides can be deadly if they push you into terrain traps.
A persistent weak layer of facets buried 2 to 3 feet deep (video) is slowly getting stronger and becoming harder to fracture in our stability tests. We still need to keep an eye on it, especially if the snowpack is thin and sugary. Riders in Taylor Fork backed off a steep slope on Sunday when they noticed their tracks were chewing through sugary, faceted snow at the ground. These thinner, weaker spots are where avalanches can be triggered.
Overall the stability is good, but not perfect. For today, the Avalanche Danger is rated MODERATE on all wind-loaded slopes. On slopes lacking a wind-load, the Avalanche Danger is MODERATE if it is steeper than 35 degrees and the Avalanche Danger is LOW on less steep terrain.
The next advisory tomorrow morning at 7:30 AM. If you have any snowpack or avalanche observations, drop us a line at email@example.com or call us at: 406-587-6984.
