Avalanche Summary

No new avalanche activity has been observed or reported.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

On the northern and eastern slopes in the alpine and at treeline, about 5 to 10 cm of new snow still remains dry above the March 31 crust. On the southern and western slopes, the snow on the surface is transformed by the sun and the heat of the day and refreezes at night. Just below this recent snow, a solid loaf of crusts 20 to 30 cm thick supports the weight of a person. Deeper, the snowpack is generally moist, even wet, down to the ground.
