Variable winds M-S forming new windslabs 10-30cm deep. This overlies pressed surfaces and old hard windslab 10-30 cm deep, or Feb crust. Feb 15 crust is 1 cm thick and exists to tree line all aspects and higher on solar aspects. Well settled midpack. Facets above Dec 4 crust, beginning to break down, buried 150-200 cm.

Avalanche Summary

A natural cycle to size 2 was observed along the Akamina Parkway yesterday. The cycle included both windslabs and dry loose avalanches. Thanks for the great observations on the Mountain Information Network, we love seeing your adventures.
