Snowpack Summary

Moderate snowfall and strong winds forecast for Friday night will create new wind slabs and continue to bury an assortment of old snow surfaces including crusts and surface facets. The crusts exist 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. Facets may also exist in combination with crusts. The mid and lower snowpack are strong and well settled. The average treeline snowpack depth is about 240cm.
