Glacial Flour

Have you ever seen a photo of a mountain lake that has bright turquoise blue hue? This gorgeous phenomena is explained by Garrett! There are a few lakes in Glacier National Park you can witness this incredible sight, but most require you to earn the view with a hike!

Garrett, what’s with all the Lakes out here? Why do they have that bluish tint to them? Yeah. Great question Anthony, we get that a lot at Glacier Institute. So if you look at some key lakes on the park like Cracker lake or even Avalanche Lake when looking down from the top they had this really cool powdery blue color that comes from a material known as glacial flour that is suspended sediment that’s left over basically ground and tilled up soil and rock that suspended in the water column. Nice, that’s really cool.
