Abstract
Large scale glacial flutings cover an area of 4 x 1.5 km on the northern shore of Harefjord in the interior
Scoresby Sund fjord complex. The flutings are modelled in coarse sandstone and conglomerates, a few
small features are probably composed of till. The ridges measure up to' 2000 m in length and 5 m in height
and occur between 50 and 250 m above sea level inthe gently sloping lowland area adjacent to the fjord.
They were probably formed beneath the lateral part of the former Harefjord-Glacier which receded
rapidly in the fjord and exposed the area at c. 7500 years BP.
Large scale glacial flutings have not been recorded before in Greenland, but seem to be of common
occurrence in parts of North America. They have probably been formed near the margin of actively
moving glaciers, and secondary flow in the basal ice may have played an important role
