Flexural slip folding in the Canadian Rockies of Alberta, west of Calgary. The Canadian Rockies are part of the North American Cordillera, a mountain belt that extends southward from Alaska along the plate margin. Uplift of this range occurred from late Jurassic through early Cenozoic. Deformed rocks are Carboniferous carbonates. Photo ID 697
