That ice cave is 1. any cave in rock that is partly filled with ice. the term should not be applied to glacier caves. the ice may form in massive icicles and flows, when percolation water from unfrozen rock seeps into a cave containing freezing air drawn in from outside. this is a seasonal situation in many alpine caves, and if winter freezing exceeds summer melting the ice may become permanent, as in austria's dachstein and eisriesenwelt caves. alternately water vapor may crystallize out as hoar frost, commonly forming large hexagonal ice crystals that line the walls of a freezing cave, as in grotte valerie, northern canada [9]. 2. a cave, generally in lava or limestone, in which the average temperature is below 0řc., and which ordinarily contains perennial ice. ice may have the form of stalactites, stalagmites, or flowstone [10].

An external model of speleogenesis during Quaternary glacial cycles in the marbles of central Scandinavia
Abstract:

The marble caves of the Central Scandinavian Caledonides were formed from open fractures that were created primarily by deglacial seismicity at the culmination of each of the many complex Quaternary glaciations that the region has experienced. Subsequent inundation by deglacial ice-dammed lakes enabled phreatic enlargement by dissolution, with passages either becoming relict during the following interglacial or else being entrenched by (mainly) vadose processes if recharged by allogenic streams. Because the distance of the contemporary fractures and therefore the cave passages from the nearest land surface is commonly constrained to be less than one-eighth of the depth of the local glaciated valley, the caves are rather epigean in nature. This subsurface cave distance is of the same order of magnitude as the thickness of rock removed from valley walls and floors at each major glaciation, suggesting that, when viewed over several glacial cycles, caves are involved in a race to develop deeper during deglaciation and the following interglacial before their upper levels are removed by erosion at the next glaciation. Indeed, relatively few cave passages in the study area can have survived from the previous, Eemian, interglacial.
This paper examines evidence for the interglacial and erosional processes and utilises a 'black box' approach to provide an external model for cave development and removal. It proposes that Caledonide marble caves in stripe karst outcrops should especially be considered as four-dimensional objects throughout their commonly intermittent existence. Mainly vadose caves are regarded as 'half-cycle' caves that developed primarily in the Holocene. Relict caves (primarily phreatic) and combination caves (with both phreatic and vadose elements) are commonly 'single-cycle' caves that developed their relict phreatic passages during Weichselian deglaciation, and only a few are 'multi-cycle' caves that have experienced several Pleistocene glacial cycles. The existing caves are more numerous and commonly larger than those that were present during previous interglacials.
