special announcement TONIGHT, Thursday at 6:00pm - The Utah Adventure Journal Speaker Series presents professional skier Brody Leven, who will share the story of his incredible adventure to climb and ski the northernmost active volcano in a 36-hour push from his sailboat base camp. More info HERE. Tuesday, February 9th - Companion Rescue at Weller Recreation from 6:30-9pm. For more info HERE. Wednesday February 10th - Avalanche Clinic for Ice Climbers. For more info click HERE. There are still a few spaces in the Women’s Backcountry 101 avalanche classes at Brighton this weekend and Snowbasin in 2 weeks. For more info on those classes and other education offerings through out the state, check out our Education Page. |
current conditions Temperatures this morning are in the single digits to low teens F. Winds increased since yesterday and this morning were blowing 10-15 mph gusting to 30 mph from the W and SW. Cold temperatures, new snow, and limited sunshine have made great riding conditions on wind sheltered slopes. |
recent activity We are saddened by the avalanche death of a backcountry skier who was killed Sunday, along the Park City ridge line. A preliminary report is HERE. We visited the site yesterday and will have more information posted in coming days. Avalanche activity yesterday involved fresh wind slabs triggered during ski area avalanche reduction work with ski cuts and explosives. |

description
It's hard to drop the danger due to wind slabs with more strong winds occurring this morning. I doubt they have as much new snow to transport as they did early this week, and fresh wind slabs shouldn't be as widespread. Since early this week, winds have blown from most directions. This morning they were blowing from the SW and W but will shift back to NW later today. For these reasons, watch for and avoid any areas with wind deposited snow. |

description
In many places the snowpack is getting deeper and stronger. There are some faceted layers in the upper 2-3 feet of the snowpack. The weakest is a spotty layer of facets (and maybe some surface hoar like Trent found in Broads Fork) buried under new snow from this weekend and this week. This layer should be mainly a problem where it is capped by a wind slab. Fortunately, you can dig into the snowpack a few feet deep and quickly look for and assess these layers. Facets near the ground cause the deep slab avalanche problem. They produced Sunday's fatal avalanche in a place where the snowpack was 2.6 feet deep and a similar avalanche in No Name bowl on Tuesday. While these avalanches are several days old, this type of problem persists for a long time and doesn't go away as quickly as we'd like. It's a tough problem to forecast for and manage in the backcountry. Regardless of the danger rating, what we want to see is an extended period of time without any reports of avalanches breaking at the ground. Until then, upper elevation slopes facing W through N through E should be assumed guilty. |
weather It’s going to be another cold day with out much warming – 10,000’ temperatures will stay in the single digits and 8000’ temperatures warm to near 15. The northwesterly winds will increase today, especially along the higher ridge lines, where averages to 35 mph, with gusts to 50 mph are possible. Mid elevation winds speeds will average 15 mph by this afternoon. Clouds and winds will continue to increase tonight through Thursday, as a small disturbance brings a few inches of snow on Thursday. |
