WORLD'S LARGEST ICE CAVE
EISRIESENWELT, AUSTRIA
WORLD OF THE ICE GIANTS
The Eisriesenwelt (German for "World of the Ice Giants") is a natural limestone ice cave located in Werfen, Austria, about 40 km south of Salzburg. The cave is inside the Hochkogel mountain in the Tennengebirge section of the Alps. It is the largest ice cave in the world, extending more than 42km and visited by about 200,000 tourists every year.
Eisriesenwelt Cave was created by the Salzach river as it flowed through the mountain eroding passageways nearly 100 million years ago. Over the course of thousands of years cracks and crevices in the limestone became more developed as water eroded the rocks away. In winter, when the air inside the mountain is warmer than outside, cold air streams into the mountain and reduces the temperature of the lower areas of the caves to below freezing point. In spring the water from melting snow seeps through the cracks in the rock and when it reaches the colder lower areas of the caves it freezes and turns slowly into the wonderful ice formations visible inside the caves.
