Recent snow and warm temps have formed a "settlement slab" at lower elevations. This slab sits on a very thick layer of weak facets, and is prone to human triggering.

Avalanche Summary

Avalanches have been occurring almost everyday this week. This is the time to avoid all avalanche terrain.

Snowpack Summary

Extreme winds on Thursday have continued to add to the wind slab problem. All S, E and N aspects have wind slabs at Alpine and Treeline elevations which rest on the delicate Jan 30th interface made up of facets, sun crust or a dense slab layer. At lower elevations, there is also a storm slab or "settlement slab" that overlies the Jan 30th layer. All elevations show snowpack conditions that are sensitive to human triggering. Travelling at lower elevations involves ski penetration to ground if you leave any established trail.

You take all this and then add a high freezing level and sunny skies. You now have conditions that are even more prime for human triggering of avalanches.
