Another 10-20 cm of new snow today brings the storm snow total to 40-60 cm. Moderate to strong winds have created touchy windslabs in the alpine and at treeline. Basal facets, depth hoar and the october rain crust are prominent at the base of the snowpack.
Avalanche Summary
Avalanche control work today on the Sunshine road produced large avalanches (size 2.5-3) on 6 of 9 shots. These avalanches appeared to initiate in the storm snow and step down to the October crust. Similar reports from the Sunshine avalanche control team and a report of a size 2.5 natural near Bow Summit indicate widespread instability.
