Banff would not be my choice for a Christmas trip. The best ski mountain there, Lake Louise, averages a modest 300-500cm snow per season, so its best terrain is not likely to be adequately covered by then. Living in a similar climate to yours (Southern California) I wouldn't be too excited about the -15C to -20C temperatures often encountered at that time of year either. Sunshine is equally frigid, but does get 600-800cm. However, it is a medium sized, mostly intermediate mountain, and I wouldn't devote nearly half of a 2 week trip to it when there are so many other great ski areas in western Canada. <BR> <BR>You should head south to the more moderate climate and higher snowfalls of the Kootenay areas along the U.S. Canada border. I second Marc's endorsement for Castle and Fernie, 2.5 and 3.5 hours from Calgary. From Fernie, Big Mountain in Montana is 2+ hours south and Schweitzer in Idaho is 3 hours southwest. <BR> <BR>5 hours west of Fernie along Canada's Hwy 3 is Rossland, home of Red Mt., a serious skiers hill of 2,900 vertical feet. Small but powder laden Whitewater is an hour north of Red near the town of Nelson. Also near Nelson are a few new snowcat operators, Retallack, White Grizzly and Baldface, where you could get a day or two of really deep powder. All of the places I've mentioned average at least 700cm snowfall, with Fernie and Whitewater close to 1000cm. <BR> <BR>Panorama is low in snowfall like Lake Louise and unlikely to have its best runs open at Christmas. Kicking Horse is undoubtedly better, but it too is on the leeward side of the Purcell Mts. and is probably best later in the season. <BR> <BR>I have published detailed resort guides for Lake Louise, Castle and Fernie (also Big White and Whistler) at <A HREF="http://members.aol.com/crockeraf/insdtrak.htm" TARGET="_top">http://members.aol.com/crockeraf/insdtrak.htm</A>. <BR> <BR>The Kootenay region has been terrible all season this year, but I have read reports that it's about a 1 in 50 year event. Base depths now are half of the next worst season of the last 15 years. Banff is just as bad, and was comparably rocky in 1993 and 1998.
