Our snowpack is losing its strength a little more each day. Watch for buried hazards as the snowpack becomes weaker.

Snowpack Summary
Not a lot of change out there in the last 24 hours. The cold snap has continued (-32 at Burstall parking this AM) which will keep the faceting trend going strong. Below treeline has nothing in the way of avalanche concerns. Treeline still has those surface windslabs in open, wind exposed areas. The cold will eventually lower the windslab problem, but for now they are front and center as the main treeline avalanche problem. They are 10-20cm thick, and because of the rotten snow underneath propagations may be surprisingly large The Nov 12th crust is down up to 60cm and is still intact, but sugary facets are immediately above and below. One more thing to ponder...above the Nov 12th there is a healthy layer of facets. It's thought that this layer will be entrained by any avalanche that may occur in the windslabs. Food for thought when thinking of a larger piece of terrain.The Alpine. Same as treeline, but a thicker surface slab. Awhile back we had a buried windslab that was an issue. In the last week or so that has blended with the the surface snow to create the current windslab issue. Snow depths are: Burstall Pass 90cm, Mud Lake 35, Aster Lake 90cm
