💙 **Yes, the water really is that colour.**
If you've ever stood beside Lake Louise, Peyto Lake, Moraine Lake—or one of the many other brilliant blue-green lakes in the Canadian Rockies—you've probably wondered the same thing:
**What makes mountain lakes so incredibly turquoise?**
No, it's not Photoshop. 😉 And it's not simply a reflection of the sky.
The answer begins high in the mountains, with glaciers grinding away at rock—and involves tiny particles so fine they can remain suspended in the water.
I've just published a new article exploring the science behind those extraordinary colours, why some lakes are bluer or greener than others, why their colour changes through the season, and why you won't find quite the same effect in every mountain lake.
Once you understand what's happening, I think these lakes become even more remarkable.
