Snowpack Summary

Large surface hoar and faceted powder on sheltered shady slopes, and a hard crust on sun-exposed slopes, may have been buried in the past week by very light amounts of new snow. Since then new surface hoar formed and loose surface snow continued to facet. A thick hard rain crust down 10-30cm can be found as high as treeline elevations. Snow pack depths and surface condition are highly variable in wind-exposed areas. The upper and mid snowpack is generally well consolidated, but basal facets and depth hoar near the ground gave recently produced hard but sudden compression test results at a shallow alpine site in the Duffy Lake area.
