The Athabasca Glacier is one of six glaciers that spill down from the Columbia Icefields. Glaciers are to icefields as rivers are to lakes. Glaciers are actually slow moving rivers of ice drawn down a mountain by gravity.The Columbia Icefield is on of the largest icefields on the planet. The icefield covers a massive 180 square miles. The Columbia Icefield is also a triple divide. A triple divide means that water reaches three oceans from this icefield, the Atlantic. Pacific, and Arctic Oceans.
