A 30cm+/- storm slab has formed. It sits on widespread modified rain crust surface hoar (SH) combo. Field tests gave mod to hard results on this layer in the west end of the park.
The Nov 5 crust layer is down 100cm+ and for the most part is unreactive. Keep this layer in mind in shallow snowpack locations at and above treeline.
Deep persistent slabs are best managed by:
Cornices are best managed by:
Cloudy with sunny periods and no precipitation today.
Alpine high of -8C with light SE wind and a freezing level at 700m.
Friday, Saturday will bring scattered flurries, light ridge winds and freezing levels up to 1000m.
Last weekend's surface hoar was modified by a freezing rain event Monday leaving a <1cm crust as high as 2500m. Tuesday's warm storm brought 30cm+/- heavy snow that appears to bond well to the old snow surface. Field trip tests at 2100m on both S and N aspects gave Mod results in the storm snow and Mod to Hard results at the rain crust interface.
Tuesday's storm brought a widespread avalanche cycle to all aspects and elevations. Avalanche control Tuesday gave results to size 3.5. Yesterday one size 1.5 natural slide was observed out of Cougar Corner paths. This slide may have been solar triggered.
