Columbia Icefield - Canada

On the card from Canada, also from the trade with Luis, we can see the Columbia Icefield and Athabasca Glacier.

The Columbia Icefield is an icefield located in the Canadian Rockies, astride the Continental Divide of North America. The icefield lies partly in the northwestern tip of Banff National Park and the southern end of Jasper National Park. It is about 325 km² in area, 100 to 365 metres (328 to 1,197 ft) in depth and receives up to seven metres (275 in) of snowfall per year. The icefield feeds eight major glaciers, including the Athabasca Glacier.

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 2–3 metres (6.6–9.8 ft) per year and has receded more than 1.5 km (0.93 mi) in the past 125 years and lost over half of its volume. The glacier moves down from the icefield at a rate of several centimetres per day. Due to its close proximity to the Icefields Parkway, between the Alberta towns of Banff and Jasper, and rather easy accessibility, 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. Hidden crevasses have led to the deaths of unprepared tourists.

The glacier is approximately 6 km (3.7 mi) long, covers an area of 6 km2 (2.3 sq mi), and is measured to be between 90–300 metres (300–980 ft) thick. - in: wikipedia
