Lake Pukaki

The blue color in New Zealand’s Lake Pukaki captured here is actually how this lake often appears. Lake Pukaki sits just east of the Southern Alps on New Zealand’s South Island and is supplied by water coming from the country’s longest and largest glaciers.

Those glaciers grind up rocks from the mountains into tiny particles we call “rock flour”. That flour is carried downstream into Lake Pukaki, where it remains suspended and gives the lake a pale blue hue

In the distance behind the lake you can see the source of some of that rock flour, Aoraki, the highest peak in New Zealand.
