A short account is given of the Late Pleistocene deglaciation and drainage in an area of Jotunheimen (fig. 2). Already at the beginning the mountain tops emerges through the ice sheet, and it is possible to follow the developing deglaciation from the distribution of deposits and erosion marks (fig. 1). These features were more and more influenced by the land forms, during this period. Different, more or less distinct, stages of drainage were established, to which the various features can be assigned: 1. Water from Veodalen drained to Rindtjørngjelet through the gap between Rundhø and Fuglhø (fig. 3) and continued, probably subglacially, to the northeast. 2. In this stage, some large river beds formed as melt water drained from Veodalen, to Rinddalen through the gaps between Fuglhø and Gråhø. This indicates that the ice surface had a dip to the northwest. A sketch (fig. 4) shows the morphological elements and their position at Blokkshaugene. Melt water came out the river bed that ends at A and continued out into the ice, which probably was covered by superficial moraine.Then the water continued subglacially, forming the kames B and the eskers C. 3. The large kame-terraces on the northern side (fig. 6), and the lateral drainage channels on the southern side of Veodalen (fig. 7) were probably formed when the water from Sjodalen drained to Veodalen. 35370
