Comments
I noticed this slide on my hike to the Pfeifferhorn today. It must have been triggered by a skier a couple days ago. I didn’t go out of my way to investigate, so all the information is basically based on that picture. Small slide and somewhat surprising with the current low snowpack. The skier probably has more accurate information.

Comments
Update from UAC Staff: This likely snowboarder-triggered avalanche on a NE aspect near 10,600' was ~13" deep, ~150' wide, and ran about 200 vertical feet. 4-6" of dry, wind-packed snow initially was triggerd and stepped down to the 8-10" of the weak faceted grains that make up the majority of the snowpack in this basin. While there are various, thin melt-freeze crusts mixed in from our warmer periods earlier this month, the snowpack is made up of a majority of FCs of various sizes. See more here.
