Snowpack Summary
Forecast new snow and strong winds are expected to create small wind slabs in wind affected terrain at treeline and above.Weak layers buried around March 19th are roughly 40 cm below the surface (up to 100 cm in deeper snowpack areas). These weak layers include surface hoar on shaded aspects at high elevations and hard crusts on solar aspects and below treeline.Sugary facets may be found near the base of the snowpack in shallow, rocky snowpack areas on shady aspects.
