Icebergs fill up lake

Massive icebergs have filled up at least a quarter of the meltwater lake at the foot of New Zealand’s largest glacier, the Tasman. The lake started to form in the late 1970s as the glacier rapidly retreated — fuelled largely by a warming climate — and it is now about 6km long. Glacier watchers estimate the latest release of ice from the Tasman Glacier, the ice river that flows past Aoraki/Mt Cook, extends at least 1.5km.
