BOTTOM LINE

Danger by aspect and elevation on slopes approaching 35° or steeper.

Danger Rose Tutorial

MODERATE avalanche dangers can be found in the Mountains of SE Utah at this time. Snow coverage can best be described as "bony" as we drop below 100% of normal snowpack for the first time in a month or so. Many areas are unsupportable, crusty and just plain bad. Reports of good skiing in limited areas - mostly shady aspects near treeline - are coming in, but ground hazards are substantial especially in the N. Woods. Heads up in there and consider using your rocks skis until we get more snow.

CURRENT CONDITIONS

As our total snowpack levels dip below 100% the reality of skiing in the desert is becoming clearer. Good skiing and riding conditions are very limited at the moment. There ARE places where decent skiing and riding conditions can be found, but higher elevations, or just the right mix of coverage and aspect are required. Despite measuring 20 inches of new snow on New Years Eve Day, the snowpack in the SE Utah Mountains remains very thin. It takes a lot of 5% density snow to achieve much coverage in the long run. In the thinner snowpack areas (plenty of those) the snowpack is too rotten and sugary to support snowshoes, skis or anything else and ground hazards are severe. South and West facing slopes are crusted over by the sun and above treeline, conditions are super variable. We need more snow, and there's a chance for more Wed/Thurs and again at the beginning of next week. Right now, we have 31 inches of snow at our Gold Basin Study Plot at 10,000 ft., and only 18" at the Snotel site at 9800'

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 Friday 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.

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

Keeping the Avalanche Danger Rating at MODERATE for the next forecast window.Over a week has passed since our last precipitation and the snowpack has had time to adjust to the load. Winds from last week 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. Remember, MODERATE avalanche danger does not mean no avalanche danger. Human triggered avalanches are still possible at this rating. Rounded, lens shaped wind deposits on E-NE-NW facing terrain are likely trouble spots.
