During the last Ice Age, more than 30 per cent of the Earth’s surface was covered by glaciers –frozen rivers of ice that move very slowly. Today as much as 10 percent is covered with glaciers.
The Lambert-Fisher Glacier is the longest in the world and was discovered (from the air) in 1956. The longest glacier in North America is the Hubbard Glacier, Alaska, Which measures 146 km (91 miles). The longest in Europe is the Aletsh Glacier, Switzerland, at 35 km (22 miles).
