Well, you can only see one of the three lakes here. This painting was done from a photo of our hike that we did some time back. It is a very nice hike, lots to look at. You know how some hikes have no visual interest, just boring switchback after boring switchback...well this one is worth the effort. Unfortunately, we went went the mosquitoes were going crazy and we couldn't pause to catch our breath. When we got to the end, the third lake, there was an icy wind blowing down Matier glacier that feeds the aqua-blue lakes but at least it kept the mosquies off!
The opaque aqua colour of the lakes is caused by "rock flour" which is silt that is carried down by the glacier and held in suspension in the water. The particles reflect the green and blue wavelengths of light.
