Avalanche Summary
You could trigger an avalanche where Sunday’s storm formed new slabs over weak snow on steep shady slopes near and above treeline. The most concerning spots are where you find old, stiff, wind-drifted snow sitting above weak snow near the ground, because this means you could trigger a larger avalanche that fails deeper in the snowpack. You could also trigger an avalanche from a distance.
Move to lower-angled terrain or sunnier slopes if you experience any cracking or collapsing underneath you.
