Because it is hard to imagine how far 13km is we measured our school field. The field is about 100 meters long. That means we would have to walk up and down the field 130 times.
The field we measured was 70 meters wide.
The Fox Glacier cover 36 square km. Would need over 5,000 of our school fields to cover it.
It is amazing to think that a glacier is a moving river of ice.
In 1966 scientists thought there were 370 glaciers in New Zealand, but in the 1980's there was a systematic count of glaciers in New Zealand and there are 3,100. There are even glaciers on Mt Ruapehu. One of glacier can be found inside the crater. Imagine that a glacier inside the crater of an active volcano.
Next time you drive along the desert road keep an eye out - you might be able to spot one of the 18 glaciers.
