Franz Josef Glacier / Kā Roimata o Hine Hukatere is a 12-kilometre long jigsaw of ice and rock, tumbling some from a névé 2500 metres above sea level—where the ice is 300 metres thick—to 300 metres above sea level, in the middle of the rainforest. It once extended all the way to the sea (19 kilometres away). Today it is three kilometres shorter than it was a century ago.
