Snowpack

We dug several pits below and near treeline on north and northeast aspects. All pits revealed the February 2nd buried surface hoar or facet layer to be between 5-8cm thick buried 20-60cm below the surface. These layers were not generally reactive to stability tests. This layer sat atop P to K hard layers that ranged between 18 to 30cm in pits below treeline and almost 40cm near treeline. Ski penetration ranged from 10-20cm and boot penetration ranged from 24-40cm. Extended Column Tests (ECTs) below treeline on northeast aspect produced ECTX and ECTN9@97cm (the interface between F hard layer and 4F weak layer). Compression Tests (CTs) on north aspect below treeline produced CT14@105cm, CT19@95cm, CT12@105, and CT9@10cm, all on weak layers of buried surface hoar or depth hoar. ECTs on northeast aspect near treeline above a 40cm knife hard layer produced ECTN19@105 and ECTN16@105. Propagation Saw Test (PST) scored PST 85/100 End on F+ weak layer 35cm below the snow surface.
