Variety of climates
The most comprehensive information is at 'http://en.wikipedia.org/wiki/franz_josef_glacier.' The glacier known as Franz Josef (or Ka Roimata or Hinehukatere) is 12 kilometres long, less than 300 meters above sea level and only 19 kilometres from the Tasman Sea. The Waiho River, which rises from the glacier, flows into the Tasman Sea. The glacier moves back and forth in four year cycles depending on the amount of snow in the upper snowfield. There are years that the glacier can extend 100 meters and others only 30.
