Pituffik is a former settlement in northern Greenland , located at the eastern end of Bylot Sound by a tombolo known as '' Uummannaq '' , near the current site of the American Thule Air Base . The former inhabitants were relocated to the present-day town of Qaanaaq . The relocation and the fallout from the 1968 Thule Air Base B-52 crash in the vicinity are a contentious issue in Greenland 's relations with Denmark and the United States
