Yes, the hazard is listed as Low, but this is due to the unlikely probability of triggering an avalanche; the consequences haven't changed as a slide can break down 1-2' deep, and well over 100' wide.
Despite the Low hazard, there are plenty of slopes I - and many other savvy backcountry travelers I know - would still avoid due to the serious consequences of triggering an avalanche. Suspect terrain harboring this persistent slab problem are steep mid and upper elevation slopes facing north through east.
If you do choose to ride in this terrain:
- Consider the consequences of getting caught in a slide. Will it carry you over rocks or into trees?
- Be sure to expose only one person at a time on the slope, and get out of the way at the bottom.
- Pay careful attention to any bullseye clues such as collapsing or cracking in the snow. Consider it the snowpack's way of telling you to ignore the hazard rating and choose lower-angled terrain.
The image shown below is from a recent avalanche that occurred along the Park City ridgeline. Although this was a fairly small slide, it illustrates the consequences of getting carried into the trees.

As of 6 am mountain temperatures are sitting just below freezing, and winds are out of the southwest and light, averaging less than 10 mph. Even at the highest elevations gusts are only in the low teens. Our threadbare snowpack reflects the 11 straight snow-less days, and is 1-3' deep with a snow surface consisting of wind and sun crusts, as well as soft recrystallized snow.
Despite the lack of snow, winter travel in the mountains is still a joy. Travel remains supportable, and the recrystallized snow looks beautiful in the early January light.
Week in Review
[Click HERE for a more detailed report]
Friday December 29: A skier-triggered avalanche occurred in Dry Fork. This avalanche was 2.5' deep and 100' wide, running 400' vertical. It was a persistent slab avalanche, failing in faceted snow that formed during the earlier part of the winter.
Saturday December 30 - Thursday January 4: Our continued pattern of no storms with mostly clear skies. Moderate west/northwest winds were observed, particularly early in the week, but they only produced small pockets of unresponsive wind-slabs. Observers reported continued collapsing in the snowpack, but collapses were much less common than over the week between Christmas and New Years. The clear skies have helped to weaken the snowpack, especially at the surface.
It has been one week since the last reported backcountry avalanche, and only one report of a collapse on Thursday.
Mostly sunny with some passing high clouds. Mountain temperatures will rise into the upper 30's F and winds would be out of the southwest and light. Models are still in disagreement over the Saturday, uh, "disturbance", where we will be lucky to get perhaps an inch or two. Warm ridging quickly returns for Sunday, with a mild glimmer of hope for about midweek.
