According to definition ice caves are caves with permanent ice, even when the ice remaining in autumn is not larger than a felt hat. Caves in ice are called glacier caves. Although it may seem inconsistent, the distinction is made in this way. The primary factor is the formation of ice within the cave yet only its preservation is decisive in making an ice cave out of an ordinary cave. For the former cold winters are required, for the latter, however, cool summers in humid climates. That limits their occurrence in Central and Western Europe to the high mountains and highlands over 700 m above sea level.
