Bluie West 7 or Grondal was a major U.S. naval operating facility (naval base) near Ivigtut in Arsuk Fjord, Greenland. In some form, it was in operation from 1940 to 1951, although its formal establishment by the U.S. Navy was on 1 April 1943. After 1942, the proper name was Grønnedal (Danish), or Green Valley (English), but the base was also called Grondal (“groan dale”) by Americans. Bluie was the military code name for Greenland. It was three miles east of the Ivigtut cryolite mine. The location’s local name in use today is Kangilinnguit. The Arsuk Fjord approach is accessible by sea year-round, though with occasional ice-breaking assistance, and is known as an exceptionally scenic area.
