AST 1 at Hudson Bay

Today at Hudson Bay we observed around 1cm of new snow over a thin layer of previous wind effect in exposed areas. We dug a profile at 1650m on a south aspect and found 2mm surface hoar down 15cm and a 10cm 4-finger layer of 2-3mm facets (mid-Feb drought layer). We had repeated sudden moderate CT results on the mid-Feb layer, down 40cm. The total snow depth was 135cm. Notably, a size 2 avalanche came out of the back of Crater Lake on the ski line sometime during the early-afternoon. Based on crown depth from afar and the snowpack structure in our profile, it was likely a persistent slab. There was not much snow available for transport today, winds were light to moderate from the west, and we had a few moments of in and out sun, but otherwise very little input. Unsure of the trigger, may have been natural or human triggered. We saw several parties out on the Prairie today, but did not specifically notice any parties around Crater Lake. ~Stay Wild Backcountry Skills~
