Snow surface

Soft settled snow over a very thin melt-freeze crust to around 1100' on west aspect
Breakable sun crust on southerly slopes
Variable wind texture. Evidence of the north winds (blowing from the south). Mostly soft snow until ridge and then more wind crust and loading on the north side. Ridge was an interesting mixture of very hard wind affected snow, melt freeze crust on features with a southerly kick and slippery facets exposed by the wind...


No slab on the way up to the ridge with hand pits. The majority of the wind effect was in old skin tracks.

We dug hand pit at 3100' on the north side and found easy failure under the new wind slab on small facets.

We dug at 3200' on a west aspect, 23° slope. HS: 300 cm, pit depth 100 cm, CT20 (x2), ECTN19 20 cm down on small facets, CT25,CT27 45 cm down on facets/buried surface hoar, ECTN25.

We dug a quick pit at 1550' on a north aspect, 25° slope. There were a couple of layers of wind slab with small facets between the two and below. This was the most most loading we could find from the previous day's wind event. CT15, CT13 25 cm down, ECTN13, CT20, CT25 40 cm down, ECTP27.
