The Columbia Icefield is located in the Canadian Rockies, astride the Continental Divide of North America. The icefield lies partly in the northwestern tip of Banff 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 8 major glaciers.
A very good friend of mine worked there until this past winter when she left to go back to school. She started there driving the big ice mover buses http://www.explorerockies.com/columbia-icefield/ and then moved on up to management. I thought she might be missing it since it would be time to go back to the glacier for the 2011 season, so i just sent her this postcard.
If you ever get to Alberta it is an amazing experience to take the bus on the the ice. Then you get to walk around the ice and if you have enough energy you can hike up from the bottom and see the end of the glacier.
