Recent Avalanches

Poor Snowpack Structure

Travel was limited and in mid elevation protected terrain, and subsequently no wind slab development from the storm was observed. Recent avalanches in the past 5 days and the poor snowpack structure observed, continue to validate a low probability and for high consequence concerns. Snow pits identified similar structure as that found in the Silverfork incident. ECTN at 38 cm up in slightly rounded large grained facets. CTM scores validated this weakness and collapsing was identified in these tests. Pits were at 9100 feet on NNE and NE aspects with slope angles ranging from 25 to 35 degrees. Of minor concern was the fact that Tilt Tests continue to identify a reactive layer 40 cm down at the interface of the event that occurred on the 20th. The last two events have now settled out to this location in the snowpack. It is likely that small grained NSF's were preserved in this isolated and protected location.
