Snowpack Summary
Recent storm snow 40-100 cm has buried a variety of old snow surfaces including surface hoar, facets, crusts, stiff wind slab and a melt/ freeze crust below 1600 m. The deeper storm snow amounts exist in the Shames/ Terrace area with less accumulations further North and East. The new snow will likely have a poor bond to these older surfaces. Below this layer, the snowpack is generally settled and strong with the exception in shallow snowpack areas around Bear Pass and Ningunsaw where basal facets remain an ongoing concern.
