This Cave in Austria Hides Ice Formations That Have Been Growing for Thousands of Years
Eisriesenwelt in Austria is the world's largest ice cave open to visitors, with ice formations stretching many meters deep into the mountain.
Eisriesenwelt in the Austrian Alps is recognized as the largest ice cave in the world open to visitors — its passages stretch for dozens of kilometers into a limestone massif.
Ice forms inside the cave thanks to a specific airflow pattern: in winter, cold air flows in and freezes water seeping from the rock, while in summer the natural geometry of the passages shields those ice formations from melting.
Some of the ice walls and columns inside the cave are many meters thick and, according to geologists, formed gradually over thousands of years, layer by layer, much like the rings in a tree trunk.
Explorers of the cave in the 19th and 20th centuries initially only reached the first icy sections of the passages and for a long time had no idea that a far larger, ice-free cave system lay deeper inside the mountain.
