Kangerlussuaq Fjord is a long fjord in the Qeqqata municipality in central-western Greenland. The fjord is 190km long and between 1.5km and 8km wide, flowing from the estuary of Qinnguata Kuussua river to the southwest, and emptying into the Davis Strait. It is the longest fjord of western Greenland.GeographyThe head of the fjord is located at, at the estuary of the Qinnguata Kuussua river flowing from the Russell Glacier of the Greenland ice sheet (Sermersuaq). The fjord mouth is located at, south of the Simiutaq Island. Another, smaller waterway connects to the sea to the north of the island.Kangerlussuaq Fjord does not have any tributary fjords, with a fairly uniform coastline. Small hills of the Kangaamiut dike swarm, such as the highlands of Tarajornitsut, dominate the coast of the inner parts of the fjord, transforming into steep mountain ranges towards the mouth. In that it is different from fjords of Norway, or indeed many other fjords in Greenland, the coast of which is flanked by progressively smaller mountains.Alluvial sediments from Qinnguata Kuussua, which carries meltwater from the ice sheet give rise to a distinct emerald coloring of the fjord waters for several kilometers from the fjord head. Silt accumulation at the estuary formed patches of quicksand of variable size up to a kilometer into the fjord.
