After we stayed in Lake Louise for a few days we took a tour to visit the Columbia Icefields. It was really breath taking to see the source of the active glaciation going on in the Canadian Rockies. We actually took a bus up the slopes and got out and walked around part of the glacier. The glacier activity creates the rock flower that turns the water the beautiful green-blue colors. We also walked along the glacier sky bridge, which is total made of glass and you can see the rocks and cliffs thousands of feet below you. Going out on the walkway gives you some great viewpoints showing you the whole geological system of glaciation ! These images gives you a sense of scale for these massive mountains and ice fields.
