In the Monashees, a cornice fall was large enough to trigger an avalanche at the top of the track zone, which has propagated full path.

These avalanches failed on the early December facet/crust layer, typically 100-150 cm deep. One notable pattern is that many of these avalanches released at relatively low elevations (1700 to 2000 m) in open clearings, burns, and slide paths. In many cases, they were triggered by smaller avalanches starting at higher elevations. This layer is likely to plague our snowpack for the remainder of the season and will be a low probability but extremely high consequence result if triggered.","type":"unstyled","depth":0,"inlineStyleRanges":[{"offset":219,"length":151,"style":"BOLD"}],"entityRanges":[],"data":{}}],"entityMap":{"0":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.facebook.com/photo.php?fbid=10159910978894462&set=p.10159910978894462&type=3"}}}}
