Leavenworth and Stevens Pass Avalanche Course

Last week I worked another avalanche course for the American Alpine Institute. This turned out to be a great weekend and a great location for an avalanche course since there was some instability in the snow pack. We were able to view some of the instabilities and find some great snow for a nice ski tour. Some photos of the weekend are below.

A thin layer of buried surface hoar is located about 40cm below the surface in many parts of the Cascades.
