Beginning as the West Castle ski hill, Castle Mountain has evolved through many incarnations with its current owners celebrating their 10th anniversary -along with the Mt. Haig expansion and inauguration of the new Huckleberry Lift. In its 40 years, the resort has had its share of infamous events with massive avalanches requiring the area to be evacuated during the 1975 Canada Winter Games and the main lodge burning to the ground two years later. A March 24th reunion party will pull together "die hards" from the decades. To compile the resort's colorful history, a local community committee is collecting stories, memorabilia, vintage photos, t-shirts, trophies, and pamphlets for a book. And the bighorn sheep that were there before stretch pants and skis showed up? The area's bighorns are part of a herd of 200 plus that forages in the Yarrow Canyon and Castle drainage just north of Waterton Lakes National Park.
