{"blocks":[{"key":"6vnuk","text":"On Saturday, explosives near the Trans Canada triggered very large avalanches (size 2.5-3.5) failing on the early December facet/crust layer. This included a historical size 4.5 avalanche which started at ridgeline, created new trim lines, and destroyed mature timber. Avalanche reports also included small (size 1-2) wind slab avalanches reactive to skiers and failing naturally; and solar radiation-triggered wet-loose avalanches to size 2 on southerly aspects.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"djg41","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"i56s","text":"Between Thursday and Friday, large (size 1.5-2.5) storm and wind slab avalanches failed naturally, these averaged 30-60 cm deep, and in some cases a weak layer of surface hoar was reported at the interface.

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":218,"length":151,"style":"BOLD"}],"entityRanges":[],"data":{}}],"entityMap":{"0":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://mountainconditions.ca/reports/heads-hockey-time"}}}}
