The ice formations in the cave were formed by thawing snow which drained into the cave and froze during winter. [4] Since the entrance to the caves is open year-round, chilly winter winds blow into the cave and freeze the snow inside. In summer, a cold wind from inside the cave blows toward the entrance and prevents the formations from melting.
According to tracking records, Arctic ringed seals breeding exhibits inter-annual fidelity to breeding sites. That is, they have a tendency to return to breeding sites that were previously used. These snow caves serve as refuge from low temperatures. These low temperatures can be dangerous to pups, and the lairs also hide the seals from predators.
It is the deepest cave in Northern Europe. [26] Cave divers occasionally visit Jordbrugrotta which is the most dived cave in Scandinavia. Most of the other approximately 200 caves in Rana are not suitable for diving, and formation of caves has been limited due most of the rock being granite. Another diveable cave nearby is Litjåga.
In 1887, it was the first electrically lit cave in Europe. At about this time 7,171 square metres of the cave's known area of 8,874 square metres were reported covered with ice. The total ice volume was estimated at 125,000 cubic metres, [5] which makes it one of the most important ice caves in the world. The thickness of the ice reaches up to ...

However, many ice caves exist in temperate climates, due to mechanisms that result in cave temperatures being colder than average surface temperatures where they formed. [7] Ice plates. Cold traps: Certain cave configurations allow seasonal convection to import cold air from the surface in winter, but not warm air in summer. A typical example ...
The off-season of fall and winter can be an ideal time to visit most European countries as the weather is still tolerable, and you can usually avoid overcrowding from tourism.
A quick-hitting but potent winter storm is delivering intense bursts of snow and strong winds from the Midwest to the Northeast, knocking out power and creating dangerous travel conditions for ...
