Athabasca Cave

Athabasca Cave
by Juan Pablo De Miguel

The Athabasca Glacier is one of the six principal 'toes' of the Columbia Icefield, located in the Canadian Rockies. The glacier currently recedes at a rate of about five metres per year and has receded more than 1.5 km and lost over half of its volume in the past 125 years.
