Just saw this posted on Wenatchee Outdoors. The Pettigrew Foundation is putting on free avy classes at Mission ridge, Stevens Pass and Alpental. This weekend at Mission, Saturday is terrain, weather, slope, aspect and that kind of info. Sunday is beacon, probe, shovel training.
Info can be found at Pettigrew website or the ski area website. This is too good to pass up if you haven't had a class.
