Avalanche Summary

One size 2.5 slab on an East aspect bowl on Mt. Murray.One size 2.5 slab on an E aspect starting in the alpine on Snow peakSeveral loose dry up to size 1.5 were also observed on East aspects.The sun is starting to have a punch so it is likely that some of these recent slides are caused by solar radiation.

Snowpack Summary

35-45cm of low density snow at tree line sits on the surface while in the alpine, wind slabs cover most of the surface. The mid pack is strong at all elevations but sits on top of  weak basal facets that cover the bottom 50cm.  This basal layer is still a concern especially where the snowpack is under 120cm.  Any avalanche triggered in the upper snow pack has the potential to trigger this lower weakness.
