General Comments

Wind picks up snow from the south side of the col, and is funneled through the col (upper middle of photo). This funneling mechanism is an incredibly efficient process. At some point the slope in the photo reaches it's threshold, and avalanches.

General Comments 2

This avalanche had some velocity behind it, uphill sides of trees low in the runout were plastered with snow.
