You know that gorgeous green-blue color of the lakes in all the pictures from the Canadian Rockies?   It is even MORE beautiful in person!  And the color comes from the sediment of the glaciers, called “glacier flour”.  What happens is glacial erosion causes tiny particles of bedrock to enter the meltwater (water released by melting glacial ice).  This enters the rivers which flow into the glacial lake and create colors ranging from milky white to bright turquoise.  This phenomenon is particularly observed in the Canadian Rockies.  See this for yourself on our newest itinerary – beginning in July 2015!
