Snowpack Summary
As the sun comes out expect the surface snow to become moist.
5 to 10 cm of new snow may be sitting on large surface hoar crystals, which have grown in most sheltered areas, or melt-freeze crusts on sun-exposed slopes and at lower elevations.
Snowpack depth at treeline is 140 - 170 cm in the Knuckles. On the North Shore, depths are around 100 to 145 cm and diminish rapidly below treeline.
