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 (16 ft) per year [2] and has receded more than 1.5 km (0.93 mi) and lost over half of its volume in the past 125 years.
Around 1800, the Athabasca Glacier peaked, then went through a period of recession, and then advanced again until 1840, when it began receding until the present day. [3] The Columbia Icefield was one of the last major geological features in western Canada to be visited and recorded by Europeans, due to its isolation and harsh weather conditions ...
The glacier is a primary water source for the North Saskatchewan River. The glacier is approximately 13 kilometres (8.1 mi) long and covers an area of 30 km 2 (11.5 mi 2 ) and was measured in 1960 to be over 400 metres (1,310 ft) thick at a distance of 8 kilometres (5.0 mi) from the terminal snout.
