In sintesi

Continue to observe for signs of the weak layer buried in the snowpack. A cooling trend may make it harder to trigger, but it is still possible.

    20 to 40 cm of snow sits above variable crusts and a weak layer of surface hoar. The surface hoar is likely most pronounced in shaded and sheltered areas at treeline. This layer lingers in our snowpack and could still be triggered, where it exists.

Snowpack Summary

The upper snowpack consists of a variety of crusts and weak layers. On the snow surface, you will likely find a sun crust on south aspects but still dry snow on northerly aspects. Buried around 10 to 20 cm, a widespread crust should be found. At a depth of around 20 to 40 cm, expect to find yet another crust on south aspects and feathery surface hoar crystals in sheltered and shaded areas. The surface hoar may be most pronounced at treeline elevations.The remainder of the snowpack is generally reported as well-settled.
