Hi All,
During our trip to Aoraki/Mount Cook National Park, the last thing we did which was Tasman Glacier Lake cruise (3 hours).
The glacier is the cleanest 'rock', and black glacier will turn 'white' after sometime contacting surrounding air.
Also, the creamy blue colour of the lake water was created by glacial flour, the extremely finely ground rock particles from the glaciers. So, the glacial water is very clean. But the lake has no fish due to lack of oxygen by the glacial flour.
Thanks for looking
