This stock photo includes a woman with snowshoes looking at the snow covered winter landscape surrounding the Mistaya River with Mount Sarbach (3155 metres/10351 feet) in the background, Mistaya Canyon, Icefields Parkway, Banff National Park, Canadian Rocky Mountains, Alberta, Canada. Banff National Park forms part of the Canadian Rocky Mountain Parks UNESCO World Heritage Site. This is a fast flowing river which escapes from its source - Peyto Lake and winds its way to the Mistaya Canyon and beyond. The Mistaya River has managed to carve out the canyon with its force - high walls of hard rock remain, pitted and gauged out from river working on the soft limestone. All the time the grand rocky mountains of the Banff National Park look on.
