Ski jumping was brought to Canada by Norwegian immigrant Nels Nelsen. Starting with his example in 1915 until the late 1960s, annual ski jumping competitions were held on Mount Revelstoke — the ski hill Nelsen designed — the longest period of any Canadian ski jumping venue. Revelstoke's was the biggest natural ski jump hill in Canada and internationally recognized as one of the best in North America. The length and natural grade of its hill made possible jumps of over —the longest in Canada. It was also the only hill in Canada where world ski jumping records were set, in 1916, 1921, 1925, 1932, and 1933.
