Although the St Jacob's slide looks to have been a wind slab, it may have run on the same persistent weak layer associated with other recent avalanches in the region. The Allison Pass avalanches seem more definitively associated with this layer. Each highlights the challenging risk management scenario we're currently in.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":82,"length":4,"key":0},{"offset":88,"length":4,"key":1},{"offset":98,"length":4,"key":2}],"data":{}},{"key":"5go73","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"dfbkq","text":"On Saturday, a fatal avalanche occurred in the Duffey Lake area. This avalanche was a very large (size 3), skier triggered avalanche with significant propagation. It was triggered at upper treeline on a northeast aspect and it failed on a shallower layer of surface hoar before stepping down to the weak layer from late-January. A more detailed report can be found here. This layer was also responsible for several large skier triggered avalanches in the neighbouring Sea to Sky region.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":365,"length":4,"key":3}],"data":{}}],"entityMap":{"0":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/mountain-information-network/submissions/eb303049-32a7-403e-a768-6e731592cac2"}},"1":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/mountain-information-network/submissions/4ea569c9-969b-48be-9e41-578c214916bb"}},"2":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/mountain-information-network/submissions/c5781dc7-87d9-11ec-a2ac-fe8d7b0a742f"}},"3":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/map?panel=fatal-accidents%2Ffatal-avalanche-accident-cassiope-peak-20220205"}}}}
