Located on the boundary of Banff an Jasper National Park is the largest icefield (130 square miles) in the Rocky Mountains. Meltwater from this icefield flows to 3 oceans: the Pacific, the Artic and the Atlantic. The biggest glacier is the Athabasca glacier (the one facing the visitors’ center). You can visit the middle of the glacier with the special Ice Explorer. During this tour the driver/guide will tell you al about the glacier and let you even out of the explorer so you can see the ice up close (and personal). You can also taste some of the meltwater. Snow at this point is 400 years old or maybe even older. From the visitors’ center to toe of the glacier is a hiking trail. Along the path there yearsigns posted. Here you can see where the toe was in a specific year. Years and years ago this thing was massive and amazing. Well, even though it is much smaller now, it still is.
