From Sea to Sky Avalanche Advisory:

Avalanche Summary

No new reports in the last few days. Explosive control work targeting cornices on Thursday produced size 1.5 results and did not trigger slabs in the slopes below. This indicates an improvement in stability since last weekend, when similar work produced size 2 results, some triggering deep slabs on the rocky slopes below. 

Earlier this month, we saw significant deep persistent slab activity, both natural and human triggered. Deep glide cracks have also been observed previously but appear to be holding together in the cool temperatures.

Snowpack Summary

A dusting of new snow falls on generally hard surfaces throughout the region; old stiff wind slab at upper elevations and a crust below 1900 m and on south aspects. In the recent cool, clear weather, crystals such as surface hoar and facets have formed ontop of these old surfaces. They are expected to become problematic as snow accumulates overtop.

Remnants of a melt-freeze crust from early December may be found around 200 cm deep in the snowpack. In shallow rocky snowpack spots, it still shows some propagation and collapse to moderate to hard loading in the most recent snowpack tests. In thicker snowpack areas it has shown no results, and appears to be trending dormant... for now at least.


     Great temperatures for making snow!!
