General Comments

Today (Sunday Feb 14) we skied more ridge lines and S aspects, but triggered another, larger, slide remotely (first 4 photos--all in sun)

General Comments 3

From the top of the Sisters, we could see plenty of natural activity on E and N aspects. Some were clearly just in the new snow, some clearly stepping down into deeper layers. Many running on surprisingly low-angle terrain.

Crazy year!
