Some recent literature concerned with the freezing of water in rocks has suggested that -5?C is a possible upper limit for frost shattering to occur. This paper reviews work which suggests that -3?C may be a more appropriate value, at least for some limestones and sandstones. It is argued that freezing rate is not as as previously thought. Some care needs to be taken in applying laboratory-derived critical threshold values to field situations. Both laboratory and field experiments need to be continued and refined before the significance of rate and intensity of freezing can be related to geomorphological features.
