Athabasca Glacier is the most-visited glacier in North America. Located in Canada’s Jasper National Park, it’s one of the six ‘toes’ of the Columbia Icefield, a natural feature of the Canadian Rockies. Athabasca has receded by nearly a mile in the past 125 years, losing about 16 feet of ice each year.
