Driest Places On Earth

Dry Valleys, Antarctica

- The Dry Valleys are so named because of their extremely low humidity and their lack of snow or ice cover.
- At 4,800 square kilometres (1,900 sq mi), the valleys constitute around 0.03% of the continent, and form the largest ice-free region in Antarctica.
- Located on the western coast of McMurdo Sound.
- These valleys have not seen rainfall in over two million years.
- The unique conditions are caused, in part, by powerful katabatic winds these occur when cold, dense air is pulled downhill by the force of gravity. The winds can reach speeds of 200 mph (322 kph), heating as they descend, and evaporating all water, ice and snow.
