One of the most stunning overlooks was at Peyto Lake. If you ever go to the Icefields Parkway, this is a must see view.
The color of Peyto Lake is so blue because it’s the junction of a stream, the lake and the delta.
Water leaving the glacier is muddy with rocks, gravel and silt. As the stream slows down, most of the rubble is left behind to become a delta. Silt flows into the icy water where most of it sinks to the bottom. Fine particles of rock ground to the texture of baking flour remain suspended in the water. This “rock flour” scatters the blue-green rays of light, giving the lake its special color.
I love how Peyto Lake looks like the head of a dog.
