- Lambert-Fisher , Antarctica - 515 km
- Novaya Zemlya , Russia - 418 km
- Arctic Institute , Antarctica - 362 km
- Nimrod-Lennox-King , Antarctica - 290 km
- Denman , Antarctica - 241 km
Glaciers hold about 75 percent
of the world's fresh water . If all
the glaciers melted , the world's
sea level would rise about 70m
