special announcement Please read, please share with others - UAC/UDOT Comms plan: New Avalanche Explosives Work Backcountry Closure Procedures Going Into Effect |
current conditions Temperatures are in the low to mid teens F this morning with westerly winds blowing 5-10 mph and a few gusts of 15-20 mph. Very light snow is falling this morning mainly near Ogden. Snow from early this week has settled and become more supportable making traveling easier. Riding conditions remain great due to limited sun, limited wind, and cold temperatures. |
recent activity Yesterday a skier in East Bowl of Silver Fork triggered an avalanche 2 feet deep and 35 feet wide. It ran about 100 feet and carried the skier only about 20 feet. What’s notable about this slide is that the snow released on a rock slab. The other major activity occurred on Tuesday when explosive work in Little Cottonwood caused several avalanches 2-4 feet deep on high elevation, northerly facing slopes. These slides broke on facets at the ground. |

With generally light winds and minimal snow transport, the only slab formation has been from settling of the new snow which has been bonding with itself at the same time. Triggering a slide within the storm snow remains possible if you find a place where the slab is a bit more cohesive than the underlying snow. The last avalanches breaking within the storm snow occurred Monday during heavy snowfall. Avalanche crown in No Name Bowl from Monday (photo - M. White) |

I’m unsure how to rate the danger for the deep slab avalanche problem. This problem is persistent and remains unstable for long periods. However, I’ve dropped the danger from yesterday because this problem is not widespread and only exists in specific places. These places are mostly high elevation slopes with a northerly aspect that were either:
The best solution is to enjoy the powder on other aspects and avoid this problem. Evelyn and I found great conditions and good stability on Tuesday on a south aspect at 9900 feet and unstable conditions on a north aspect at a similar elevation in Grizzly Gulch. See video below.

weather A weak storm descending from the north today will bring cold temperatures and light snowfall. Skies will be cloudy and high temperatures shouldn’t climb out of the teens F. Winds will blow from the WNW at about 10 mph. 1-4 inches of new snow will fall today and tonight. |
