This layer is now likely about 120-160 cm deep in some of our snowfall hotspots. This layer is most prevalent around treeline elevations, but likely reaches into the alpine and in openings below treeline too. It may sit above a crust below 1600 m. Both of these layers may be significantly shallower (and potentially easier to trigger) on the east slope of the Rockies","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[{"offset":412,"length":12,"key":0}],"data":{}},{"key":"4ua8h","text":"","type":"unstyled","depth":0,"inlineStyleRanges":[],"entityRanges":[],"data":{}},{"key":"aem08","text":"This MIN report from the Powder King area on Sunday captures well that both of these layers remain a concern.
