Danger Rose Tutorial

MODERATE avalanche dangers can be found in the Mountains of SE Utah at this time. Even at 100% of normal snowpack ground hazards are, uh, pronounced. Winds have been at work and some areas are alternately stripped or loaded above treeline and there is a fair bit of wind damaged snow up high. Sheltered below treeline slopes will provide the best turning and riding conditions until we get some more snow. Maybe midweek next week.

CURRENT CONDITIONS

On our tour to Mt. Tomasaki today we experienced great views and a beautiful day. Unfortunately the beauty was only skin deep. Shallow , rotten snow and a variety of crusts await the traveler who ventures onto south facing terrain. From where we were, the shady side skiing wasn't much more appetizing. It seems like a much more shallow snowpack around the east and north side of Geyser Pass than in Gold Basin. We were walking around on 1-2 feet of snow (or less...) for the majority of our tour. The snow was surprisingly shallow considering the 20 Inch storm we had a week ago. Best to keep the turning to sheltered and more filled in areas. We are at 100% of normal based on the snowpack weight at the NRCS Snotel site, and where there is enough snow to ski or ride there are some good conditions to be found. Beware of ground hazards.

Roads are clear and passable to the trailheads. Lot's of traffic is making them slick in places. East and West accesses clear in the La Sals.

LUNA Groomers were up today and attended to the entire nordic trail system in the La Sal. The upper and Lower nordic loops, Geyser Pass and Gold Basin have all been groomed.


RECENT ACTIVITY

Nothing recent. Collapsing and cracking seem to be quieting down significantly.

Dropping the Avalanche Danger down a notch above treeline as a week has passed since our last precipitation and the snowpack has had time to adjust to the load. Winds from 2 days ago not only stripped or damaged snow above treeline but might have created a few "skier education pockets" out in the high country and our weak underlying snowpack is never to be completely trusted. We are calling the Avalanche Danger in the Mountains of SE Utah MODERATE. Human triggered avalanches are still possible at this rating. Rounded wind deposits on E-NE-NW facing terrain are likely trouble spots.
