Snowpack Summary

In general the snowpack is now well bonded. Recent light snowfall has buried an assortment of old snow surfaces including crusts, old wind slabs and surface facets. This light snowfall has been redistributed by moderate alpine winds and has formed small wind slabs on lee features. The underlying crusts have formed on all aspects at lower elevations and on steep solar aspects higher up. 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.
