Abstract

The age frequency of surface boulders on 12 avalanche boulder-ramparts in upper Jostedalen, southern Norway, was investigated using the size-frequency since AD 1325 on lichen-size-frequency distributions. The results suggest that maximum avalanche activity occurred during the 19th century, after the peak of the Little Ice Age. Close agreement between the records of snow avalanches and debris flows suggests that both reflect periods of high winter snowfall and rapid spring melting rather than low temperature. Future greenhouse warming may therefore result in increased avalanche activity in southern Norway
