To be honest, if you are just riding at the Silverton Ski area, avalanche training is not really needed. I know they "require" you to have avalanche gear and have a working knowledge of it. Have they ever had an avalanche at the ski area that has taken out guests? Nope. That is because it's controlled just like any other ski area. What they planned on doing and what really happened are two different things. Plus if you are not there during the shoulder seasons you're being guided. They are not going to take you to any spot that has any sort of real avalanche threat. Of course a slide could happen, but it's the same chance as you'd have one happening at Breck. Not to dissuade you at all. Learning how to read avalanche terrain is an awesome skill to have.
