Over the presidents day weekend, I did the first 2 of 3 days doing an Avalanche course (level 1). Last day will take place in march. As I have started doing more back country skiing, it felt like a good thing do get some additional training on. Obviously best option is to avoid getting into situations where there is likelihood of one happening, and actually that's exactly what we spent a large portion of day 1 working on. Mostly training but still got out and a couple runs near the end of the day in some nice powder.
If you are wondering - the picture of me in the hole with the shovel - this is called a compression test, where you dig a pit, and test the different layers, and how well they hold together. Interestingly when we probed the snow to the ground we were standing on about 7 feet of snow.
