The Athabasca Glacier is one of the six principal 'toes' of the Columbia Icefield, located in the Canadian Rockies. The glacier currently loses depth at a rate of about 5 metres per year and has receded more than 1.5 km and lost over half of its volume in the past 125 years. Easily accessible, it is the most visited glacier in North America. The leading edge of the glacier is within easy walking distance; however, travel onto the glacier is not recommended unless properly equipped.
