Kvithola is a system of vertical, relict phreatic karst conduits. Passage cross-sections are elliptical or
lenticular, averaging 1.5 m2 in area. The cave extends parallel with, and close to the wall of a formerly
glaciated valley. Water was transmitted downwards at a rate of 1m3s-1, and the majority of passages
were developed from sheet-fractures close to the surface. The corresponding paleohydraulic gradient was more than two orders of magnitude less than the surface slope. The only conceivable mode of phreatic flow is then by ice contact, of which the ice-marginal case seems the most probable with regard to CO2 content and hydrology of glacial environments.
