{"blocks":[{"key":"6vnuk","text":"Another round of very large (size 2.5-4) deep persistent avalanches failed naturally between Thursday and Friday, with rapid loading and warming temperatures being the likely trigger. In the same timeframe, 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.

This past week numerous very large (size 2.5-3.5) deep persistent slab avalanches occurred in both the Selkirks and Monashees. 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. Throughout each recent snowfall, the upper snowpack has been reactive as well. There have been numerous reports of size 1-2 storm and wind slab avalanches reactive to human triggering and failing naturally. (See this MIN from the Fingers) These smaller avalanches could step down to produce large avalanches in very rideable terrain.","type":"unstyled","depth":0,"inlineStyleRanges":[{"offset":374,"length":151,"style":"BOLD"}],"entityRanges":[{"offset":830,"length":3,"key":1}],"data":{}}],"entityMap":{"0":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://mountainconditions.ca/reports/heads-hockey-time"}},"1":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://avalanche.ca/mountain-information-network/submissions/dafcceb8-c5c2-4aee-b20b-420ceafa1cd4"}}}}
