I have gone through level 3 avalanche seminars in the US I would recommend saving you money and going throught the Canadain Level 1 it is alot more money time and Information then any of the US classes. If I had the time myself I would take level 1 Canadian. BTW if you intented to take a Avy class in the states and have basic info on Avy, I will contest Level 1 US and go On to Level 2. Level 1 US is pretty much just telling you what avalanche terrain is. Level two is Pits and recording. The two do overlap. Overall you can read the same info that they teach in avy books. I would highly recomend the "Avalanche Hand Book" By David McClung. I hope this info helps
