Athabasca Glacier

Part of the colossal Columbia Icefield that bestrides the continental divide in Banff and Jasper national parks, the Athabasca Glacier is the most visited in North America. It is easily visible from the Icefields Parkway, about 100 km (62 mi) south of the town of Jasper. The glacier has receded in the past 125 years but still covers an area of approximately 6 sq km (2.3 sq mi) and at its thickest, measures 300 m (980 ft). Guided tours take visitors right up onto the glacier.
