Snowpack Summary
Roughly 20 to 30 cm of recent snow has been redistributed by strong northerly winds in the alpine. At treeline and above, in wind-sheltered terrain, the new snow sits atop variable old surfaces, including large surface hoar crystals. In wind-exposed terrain and areas below treeline the new snow sits atop a widespread, thick crust.
The mid and lower snowpack remains well-bonded with no layers of concern.
