New research from the University of Alberta says the Canadian Rockies may be losing one of their most iconic features — those brilliant turquoise alpine lakes. "This summer the heat domes in Western Canada really have accelerated the rate of melting of the glaciers in the … Rockies," said professor of aquatic ecology Rolf Vinebrooke on CBC Radio's Daybreak South Tuesday. Vinebrooke explained that the lakes contain glacial flour, a sediment from rocks that slowly makes its way into the water through erosion. But as the glaciers melt at faster rates than ever before, less of the meltwater contains the rock flour, which intercepts sunlight and gives the lakes their milky turquoise luster.
