Goslin. A few size 2 avalanches were also reported in the Barkerville area. These included a mix of wind slab and persistent slab avalanches on a 40 cm deep surface hoar layer, mostly on treeline features (see some photos in the MIN reports here, here, and here). One was thought to have been initiated by a machine-triggered cornice fall. In the first week of February there was a flurry of persistent slab avalanche activity on the same surface hoar layer in the riding areas around Valemount and Blue River. Although the likelihood of triggering persistent slab avalanches is decreasing, this weak layer warrants assessment in open, sheltered slopes at treeline where this layer is likely pronounced and preserved.","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":131,"length":18,"key":1},{"offset":467,"length":4,"key":2},{"offset":473,"length":4,"key":3},{"offset":483,"length":4,"key":4}],"data":{}}],"entityMap":{"0":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/mountain-information-network/submissions/83e0bc9b-7662-42a3-8f16-b2790a8cb957"}},"1":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/mountain-information-network/submissions/f5975ac9-9dd9-4398-b832-a03dda0ead70"}},"2":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/mountain-information-network/submissions/df736481-95d6-4971-b7b8-716c8aa8ca85"}},"3":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/mountain-information-network/submissions/1407b494-5711-46d9-a904-833795008f35"}},"4":{"type":"LINK","mutability":"MUTABLE","data":{"url":"https://www.avalanche.ca/mountain-information-network/submissions/7d535bff-3285-4d4f-8d0c-b878e2fffa41"}}}}
