The Columbia Icefield is the largest icefield in the Canadian Rockies. It covers some 230 sq km to a depth of 365 m and is 28 km long. Draped over the continental divide on a high alpine plateau along the Alberta-British Columbia border, it receives an average of 7 m of new snowfall per year. Not all of that snow can melt in the short summers so it accumulates, turning to ice. This flows outward through the surrounding passes, creating fingers of ice known as glaciers, of which the Athabasca Glacier is the most well-known.
