Snowpack

Dug 3 pits off the main Tincan skin track at about 2500' on a NW facing test slope. We found about 25 cm of newish snow on top of 20-30 cm of facets which was on top of a melt-freeze crust. We also found a thin layer of surface hoar about 5cm down into the facet layer. Stability tests: 5xCTs with most breaking at either the top of the facet layer or the surface hoar layer, scores ranging from 17-30+ with Q1/2 shear quality. 3xECTN at facet/surface hoar layer and 1xECTP, all with 20+ hits
