Snowpack Summary

50 cm snow arrived  in Jan 31 / Feb 1 with  strong winds and warm temperatures. The storm created thick storm slabs over the facetted midpack and weak basal facets and depth hoar.

Avalanche Summary

Considering the depth of new snow very little natural activity seen accept in the Wilson area.  Explosives work over the last 2 days produced inconsistent results.  Icefields area from size 1 to 3 with 50 to 100% cleanout.  Loose dry results up to size 2.5 from Medicine Slabs but nothing hitting the road.

Confidence

Due to the number and quality of field observations on Tuesday
