Avalanche Course at Mount Baker with American Alpine Institute by Alasdair Turner

I spend last weekend teaching an avalanche course in the Mount Baker backcountry.  We had some great conditions for teaching an avalanche course with many unstable layers and lots of new snow.  The avalanche problems included storm slabs, wind slabs and a deep persistent slab layer.  The touring day made for some of the best skiing I have done yet this year.  Some amazingly deep snow that stayed light despite some warming temperatures.

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.

American Alpine Institute Avalanche Course by Alasdair Turner

The last couple of weekends have been spent teaching avalanche courses for the American Alpine Institute.  Although the snow pack has been a little boring, the weather has been great and it has made for some great courses.  Below are a few photos of the last two trips.

Although most of the snow was pretty solid,  Small areas of instability were found.  Here we conduct compression tests on the snow.
