Leavenworth and Stevens Pass Avalanche Course with American Alpine Institute / by Alasdair Turner

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.
