Tasman Glacier New Zealand || Mount Cook National Park

Tasman Glacier New Zealand || Mount Cook National Park
Haupapa / Tasman Glacier is the largest glacier in New Zealand, and one of several large glaciers which flow south and east towards the Mackenzie Basin from the Southern Alps in New Zealand's South Island.

At 23.5 kilometres (14.6 mi) in length, Tasman Glacier is still New Zealand's longest glacier, despite shrinking considerably from the 1990s onwards. It is as much as 4 kilometres (2.5 mi) wide and 600 metres (2,000 ft) thick, and lies entirely within the borders of Aoraki / Mount Cook National Park. The glacier covers an area of 101 square kilometres (39 sq mi) and starts at a height of 3,000 metres (9,800 ft) above sea level. Snowfall during the winter and spring seasons may accumulate up to 50 metres (160 ft). After the summer melt, 7 metres (23 ft) may remain in the high altitude glacier head.
Lower Tasman Glacier
The Tasman flows south west from Hochstetter Dome and Mount Elie De Beaumont alongside the southern slopes of the Minarets peak and south along the eastern flank of New Zealand's two highest mountains, Mount Tasman and its higher southern neighbour Aoraki / Mount Cook.

Although its upper reaches are snow-covered, rocks carried by the glacier are exposed by ablation along its course, and the lower glacier is entirely rock-covered. The rock cover helps insulate the ice from the sunlight and slows down the melting process. Tributaries in the lower parts are the Rudolf Glacier, Forrest Ross Glacier, Kaufmann Glacier, Haast Glacier, Hochstetter Glacier, and Ball Glacier.

The glacial terminal lake is met by the meltwater of the Murchison Glacier, which approaches from the northeast and flows alongside the Tasman Glacier outside the moraine wall. The waters of Tasman Lake flow into the Tasman River and flow south joining the Hooker River draining the proglacial lakes on the Hooker and Mueller Glaciers. The Tasman River exhibits a braided characteristic, and flows south into Lake Pukaki. They eventually flow into the Waitaki River and to the Pacific Ocean north of Oamaru.
