Evening Lake Tekapo NZ
The amazing turquoise blue colour of Lake Tekapo is created by "rock flour" - the glaciers in the headwaters grind the rock into fine dust. These suspended particles in combination with the sunlight create Lake Tekapo's unique water colour. Original public domain image from Flickr
