General Comments

This natural avalanche likely occurred some time during the height of this weekends storm. It has quickly started to fill-in, but it appears to have released on the buried surface hoar that has been very active in this area for a few weeks now.

General Comments 3

Today, I also observed several new snow avalanches in steeper north facing terrain. These were mostly small pockets that involved the newer snow, but some of these are running a few hundred feet vertical.
