}The volumetric expansion of freezing pore water is widely assumed to be a major cause of rock fracture in cold humid regions, but data from experiments simulating natural freezing regimes indicate that bedrock fracture results instead from ice segregation, supporting a conceptual model in which ice segregation in near-surface permafrost leads progressively to rock fracture and heave.
