In guiding, there are many hazards that one must have great depth of knowledge about to be able to mitigate risk. Snow stability is one of them. Eric works for Colorado Mountain School, and they have random study sessions based on what training is coming up. He invited me to join a group of them studying for their Avalanche Level 3 course. I have to take this course in a year or so, and this was a great opportunity to refresh some of my skills from Level 2. One of the main points I took away from this evening was know the weak layer, know what is above it, and know how this relates in time and space.
