Glossary of Karst and Cave Terms
(German.) Solution flutes that occur only in places where fresh unspent precipitation is active and end where the water attains too high a content of lime or where water is added. Their length increases with slope, temperature, and rainfall; eventually reaching 1 m and more in the tropics, up to 50 cm, and as an exception, 100 cm in the Alps. Their width extends from 1 to 3 cm. They lie together in rows with no space between, with sharp intermediary ridges of no more than 1 cm in height. They increase at all freely exposed peaks and ridges where fresh rainwater alone is at work. The grooves gradually flatten out to a smooth surface. Their theory of origin is unknown. . Synonyms: (German.) Kannelierungen; solution flutes; and firstkarren.
