Snowpack Summary

15-30 cm of new snow accumulated in the north through this week with smaller amounts around Panorama and south. The new snow has covered surface hoar in sheltered areas and various wind-affected surfaces elsewhere.

This old, wind-affected snow sits over a crust on solar aspects in the alpine or a surface hoar/crust combination around treeline. The surface hoar is down 25-45 cm and seems to be isolated to the north of the region or areas with a relatively deeper snowpack.

There are a variety of crusts buried 10-110 cm below the surface. These crusts have begun to break down. The base of the snowpack generally consists of facets and depth hoar.
