Snowpack

Snowpack: About 10-12" of total storm snow in the Anthracites. This snow was vary light and lacked a slab on most NTL and BTL slopes. A few slopes in these areas has seen previous wind effect with more cohesive slabs. The recent HST heated up quick on a south aspects as the sun came out mid day. Roller balls formed on many south aspects at NTL and BTL elevation as the sun came out. Other aspects stayed dry and cool through the day. All around good stability in areas that have seen skier traffic before the recent storm on the 13th.

Avalanches: Several natureal and human triggered loose snow avalanches on NTL and BTL slopes . One large natureal slab in East Bowl from early on the morning of the 15th.
