Notes

Skiers saw an avalanche that released shortly after the New Year's storm cycle. From the email: "Snow was good below tree line and was nuked by the wind above tree line. Lots of variability. At Hyalite Lake we looked to our right at a slope (east facing?) and there was an avalanche that probably released 2 to 4 days ago.  See attached photo. Probably 1 to 1.5 ft crown. Didn’t run far. We kept our slope angles less than 30 degrees and dug up above the lake. ECTN 22 about 40 cm down. Wind slab and new snow on small facets." Photo: K. Birkeland
