Ice Caves
An ice cave is any type of natural cave (most commonly lava tubes or limestone caves) that contains significant amounts of perennial (year-round) ice. At least a portion of the cave must have a temperature below 0 °C (32 °F) all year round, and water must have traveled into the cave’s cold zone. Terminology This type of cave was first formally described by Englishman Edwin Swift Balch in 1900, who suggested the French term ''glacieres'' should be used for them, even though the term ''ice cave'' was then, as now, commonly used to refer to caves simply containing year-round ice. Among speleologists, ''ice cave'' is the proper English term. A cavity formed ''within'' ice (as in a glacier) is properly called a glacier cave. Types Ice caves occur as static ice caves, such as Peña Castil Ice Cave, and dynamic or cyclical ice caves, such as Eisriesenwelt. Temperature mechanisms In most of the world, bedrock caves are thermally insulated from the surface and so co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dachstein Rieseneishöhle Parzifaldom 20210918
Hoher Dachstein () is a strongly karstic mountain in central Austria and the second-highest mountain in the Northern Limestone Alps. It is situated at the border of Upper Austria and Styria, and is the highest point in each of those states. Parts of the massif also lie in the state of Salzburg (state), Salzburg, leading to the mountain being referred to as the ''Drei-Länder-Berg'' ("three-state mountain"). The Dachstein massif covers an area of around with dozens of peaks above 2,500 m, the highest of which are in the southern and southwestern areas. The main summit of the Hoher Dachstein is at an elevation of . Seen from the north, the Dachstein massif is dominated by glaciers with rocky summits rising beyond them. By contrast, to the south, the mountain drops almost vertically to the valley floor. Geology The geology of the Dachstein massif is dominated by the ''Dachstein-Kalk'' Formation ("Dachstein limestone"), dating from Triassic times. In common with other karstic ...
