That's us, with the Columbia Icefield in the background (partially obscured by snow). The Columbia Icefield contains several glaciers and is the largest ice mass south of the Arctic Circle, covering roughly 130 square miles to a depth of 1148 feet. Contrary to popular belief, glaciers are not from frozen liquid water but rather get created when the amount of snowfall in a winter is more than what summer can melt away. Over time as this process repeats, the pressure from new snow compacts the layers beneath into a solid mass. The glaciers here have snow from hundreds, or in some places, thousands of years ago.
