Snowpack Summary
In general the snowpack is now well bonded. Generally light snowfall has buried an assortment of old snow surfaces including crusts, old wind slabs, surface hoar and surface facets. This light snowfall has been redistributed by moderate alpine winds and has formed small wind slabs on lee features. The crusts have formed on all aspects at lower elevations and on steep solar aspects higher up. Friday's moist snowfall may have destroyed this surface hoar in many places. Surface facets have grown particularly on northern aspects where colder temperatures have persisted and facets may also exist in combination with crusts. The average treeline snowpack depth at is around 240cm.
