What is a Glacier?
A glacier is a slowly flowing mass of ice with incredible erosive capabilities. Valley glaciers (alpine glaciers, mountain glaciers) excel at sculpting mountains into jagged ridges, peaks, and deep U-shaped valleys as these highly erosive rivers of ice progress down mountainous slopes. Valley glaciers are currently active in Scandinavia, the Alps, the Himalayas, and in the mountains and volcanoes along the west coasts of North and South America. The amazing, jagged landscape of New Zealand’s Southern Alps is also courtesy of the erosive power of glaciers. The lighting of the signal beacons in the movie The Lord of the Rings – The Return of the King [1] captures this famous landscape.
