when quantitative estimates of bedrock erosion and weathering rates are made (eg, Larsen and Mangerud, 1981; Hallet et al., 1996). One can easily imagine situations where sediment recycling has been underestimated or not recognized, with the result that bedrock erosion has been overestimated. Proglacial areas of the Jostedalsbreen ice field in western Norway were affected by numerous Holocene glacial advances (Figure 1; eg, Matthews, 1991; Nesje and Kvamme, 1991; Nesje et al., 2001). One striking observation on the glacier foreland is that the size of the glacial, depositional landforms is seemingly at odds with the present-day sediment-poor outlet glaciers of the Jostedalsbreen ice field (Matthews et al., 1979; Lien and Rye, 1988; Winkler and Nesje, 1999; Burki et al., 2009). In addition, large proportions of rounded boulders have been observed in the valleys inside the ‘Little Ice Age ’ (LIA) maximum moraine. This last observation is the focus of this paper in which we aim to explain the atypically, apparently high content of rounded boul-ders in lateral moraines. These lateral moraines were formed dur-ing the advance to the LIA maximum and during the subsequent
