First significant avalanche of the season. Two storms - 18" in late October, and 5"-7" in early November left 18" -24" of snow on the ground. Almost three weeks of high pressure in November faceted the entire snowpack. 7" of snow fell on November 28, followed by a week of erratic, slab building winds. 14" at 1.4" SWE fell during a 48 hour period between December 7-8 with moderate to strong SW winds.
