Snow surface

New snowfall is burying surface hoar sitting on an average of about 2" of facets that sits on a melt-freeze crust.
Crust consistency is variable without a noticeable pattern in our travels.


Out of the 30+ pits that were dug during the weekends course all but one had ECTX results. Just one pit on Sunburst, NW aspect at 2,000' had a result of ECTP21 down 25cm failing below the bottom most melt-freeze crust layer (this pit had 3 crust layers in the top 25cm).
Overall we observed a large variety of different melt-freeze layers in the top ~30cm of the snowpack.
