Geology innit?!

The south island is particularly special because of its geology - thousands of glaciers have carved much of the landscape, most have receeded leaving valleys and mountains with lakes and strange scars...
This is the Fox Glacier, it has retracted considerably over the past few hundred years, but has been growing on average, one metre a week since 1985!

It is also one of the few glaciers in the world which ends in rainforest... it's not tropical here, but rainforest nonetheless!
