Tasman Lake on South Island, New Zealand

Tasman Lake in Aoraki/Mount Cook National Park on New Zealand’s South Island didn’t exist until 1990. When Tasman Glacier began to melt, small glacial pools began to coalesce into a substantial body of water. As the glacier retreats an average of 590 feet a year, Tasman Lake grows ever wider and deeper. It won’t keep growing forever, though. Scientists estimate that the glacier that feeds Tasman Lake will disappear entirely within the next couple of decades.


Tasman Lake is a proglacial lake formed by the recent retreat of the Tasman Glacier in New Zealand’s South Island. In the early 1970s, there were several small meltwater ponds on the Tasman Glacier. By 1990, these ponds had merged into Tasman Lake.
