Yesterday's high clouds and stiff breeze helped abate any wet snow avalanche activity which has prolonged the endangered existence of our snowpack. However, the snowpack did absorb enough radiation on south and west facing slopes to soften up the top few inches, initiating the creation of yet another melt freeze crust on these aspects. These surface curst could become a problem if we receive more snow and wind today.
