There are many beautiful colour lakes in the mountains, thanks to the rock flour. Tiny clay particles form as rocks on the bottom and side of a glacier grind against the bedrock. Fine powder that looks like flour is formed from this abrasion, which is transported to the lakes as ice melts and rock flour is exposed.These fine particles are suspended in the water, reflecting more of the blues and some of the greens then any other wavelengths of light. Giving the glacier fed lakes their beautiful colours. Enjoyed the look of the water as I watched and took pictures of two female Harlequin Ducks on Moraine Lake few weeks back.
Until next moment,
