Prinsesse Ingeborg Halvø is a low peninsula, situated on lat. 81°35'N., long. 16°35'W. in northernmost east-Greenland. From the west it wedges into the large local icecap Flade Isblink, which forms the easternmost corner of Greenland. The peninsula lies 70 miles southeast of the northernmost region in Greenland, Pearyland, separated from it by a bay, the joint mouth of two big fjords: Danmarks Fjord and Independence Fjord. The latter cuts its way westward from the Greenland Sea as the southern border of Pearyland (Fig. 101).At three places on Prinsesse Ingeborg Halvo (Fig. 102, A, B, C) paleo-Eskimo flint implements were spotted by the author of this article during the summer of 1952. The localities were all situated at a height of 40-50 feet above sea level and at a distance of 370-810 yards from the present coastline. Thus, from a geological point of view they belonged to the same horizon in the system of old raised beach terraces of the peninsula.
