Is this a pet peeve of anybody else? The recent activity on the Vail vs. Whistler thread, with references to the Squaw "Backside" reminded me of this. (And Squaw may not be the best example, as references to Squaw's "backside" exist on the website, despite that thread being the first time I have EVER heard reference to such).
To me, calling something the "backside" of a ski area means crossing a ridgeline. Back bowls at Vail, for example. Montezuma Bowl at A-Basin. Failing crossing a ridgeline, at least skiing a different aspect than the rest of the base area. At one point the runs off of the Sunnyside lift at Winter Park were referred to as "Mary Jane's Backside," and obviously that name has as much to do with the double entendre as much as anything to do with the traditional use of the term.
What I don't get is that I am starting to hear "backside" for basically anything that doesn't funnel into an improved base area. Reference to Wolf Creek's "backside" are popping up by a specific type of visitor, referring to the Alberta area. This despite all of Wolf Creek ski area being in the same overall drainage/valley, etc.
Does your ski area have a "backside?" Is the term used in a way that makes sense? Does the ski area officially use the term?
