One of my favorite places in the world, I never get sick of watching the sunset at Moraine Lake.
I also never get sick of the incredibly vibrant blue water, which has to be seen to be believed.
The color is caused by powdered rock, known as rock flour, which is rubbed off the face of the mountains by glaciers high above the lake, and becomes suspended throughout the water.
Because the mountains in different locations are made of different combinations of rock, each lake has a slightly different hue of blue-green. Thanks to the large amount of rock flour being deposited into Moraine Lake each day, the intensity of the color is hard to believe, even in person!
Sadly, one day soon these lakes will lose their color, once the glaciers above them die, which is happening at an alarming rate.
