you're thinking of ARAC (advanced recreational avalanche course) but you were right in that you need a RAC first. There should be plenty of these offered in the Lower Mainland area. For a list of RAC providers, contact the CAA-
www.avalanche.ca. This is also prerequisite to taking the CAA Level 1 which in turn is necessary to have before taking CAA Level 2, that and a whole bunch of experience and recommendation from a Professional member of the CAA. As for books, here's a couple that were not mentioned:The Avalanche Handbook by McClung & Schaerer, Avalanche Accidents in Canada Vol 4 1984-1996 Jamieson & Geldsetzer, Backcountry Avalanche Awareness by Bruce Jamieson, Sledding in Avalanche Terrain by Jamieson & Sverdus, Free Riding in Avalanche Terrain by Jamieson & McDonald
Staying Alive in Avalanche Terrain by Tremper is right there with these.
