Snowpack Summary

The snow surface has been heavily wind affected. You will likely find a variety of hard slabs, wind-pressed snow, sastrugi, and melt-freeze crust where the wind has scoured down to it. In sheltered areas below treeline, you may find pockets of soft snow that overlies a thick melt-freeze crust. In the south of the region, the remainder of the snowpack is well-settled.Around Bear Pass and in the north of the region, you may find two or three weak layers of feathery surface hoar crystals buried between 50 and 100 cm. The base of the snowpack may also be composed of weak and sugary faceted snow.
