current conditions Looks like we picked up a little taste of snow overnight, and it's wicked cold in the mountains this morning with 3 degrees below zero at the UDOT Hwy 89 summit and 4 below at the CSI Logan Peak weather station. I'm reading fairly moderate west winds averaging in the upper single digits. With very shallow early season snow conditions, rocks and dead-fall are only shallowly buried and you need to be extra careful and keep your speed down in the backcountry. The extremely cold air temperature is causing a significant temperature gradient through the shallow snowpack. This difference in temperature is driving sublimation of water vapor through the snow, and rapid development of weak faceted snow. I was impressed Monday by how quickly this is occurring, especially where there is less than about 2' of snow cover.
Still a bit shallow to ride on most slopes in the backcountry, so the weakening snow remains untracked, untested, and undisturbed.

recent activity A skier remote triggered a wind slab avalanche Sunday afternoon as he was walking along the east ridge of Chicken Hill in the Bunch Grass drainage. Drifting Sunday created sensitive wind slab avalanche conditions in exposed terrain. (12-4-2016) |

description
In some areas drifts formed earlier in the week on small-grained near surface facets. This granular sugary snow is known to often become a persistent weak layer, and in some cases, the wind slabs are likely to remain unstable for a little while. |
