particularities

Glacial lake

The Tasman Lake is a glacial lake formed by the retreat of the Tasman Glacier on the South Island of New Zealand was established.

There were several small meltwater lakes at Tasman Glacier in the early 1970s . By 1990 these had merged to form Tasman Lake .

The Tasman Lake accelerated in the wake of the withdrawal of the Tasman Glacier. Initially, the lake washed away the glacier front, which then broke off. Now there is a 50–60 m wide front of glacier ice below the water level, from which regular icebergs break off and drift out onto the lake. This means that more glacier ice is in contact with the water, which increases the rate of melting. In 2008 the lake was 7 km long, 2 km wide and 245 m deep. It is expected to reach 16 km in length over the next one to two decades.

The Tasman Lake, the glacier and the surrounding mountains are part of the Mount Cook National Park .

Boat trips for tourists are offered on the lake. The Department of Conservation offers three to five-day stays for school classes as part of the learning outside the classroom, which is customary in New Zealand schools .

The lake is named after the Dutch explorer Abel Tasman .
