Kulusuk Island is an island in the Sermersooq municipality on the southeastern shore of Greenland. It is an outlying island in the Ammassalik archipelago of islands on the coast of the North Atlantic. The island is home to Kulusuk, the fourth-largest settlement on the entire eastern coast of Greenland. The island has an area of 41.98 km², and measures from north to south and from west to east. The Kulusuk Airport on the island is one of the two airports on the entire eastern Greenland coast.
History
Among the archaeological ruins on Kulusuk the ancient settlement of Ikaasap Ittiva is located near the shore at the northern end of the island. This site belongs to the oldest phase of the Saqqaq culture, around 2000 BCE.
The coast of most of the island is mostly undeveloped, with the mountain walls and slopes falling directly into the ocean. In the west there are several small peninsulas and bays. The largest of the latter is Tiivtingaleq bay to the southwest of the settlement, host to a small harbour used both in all seasons as a starting point for hunting trips. A group of tiny skerries surrounds the coastline in the west, as well as in the north in the vicinity of the village. From north to south, the western skerries are: Sitte, Puullortuluk, Ittitalik, Ittive, and Saattit.
Mountains
The island is hilly, and unlike its immediate neighbours, not glaciated, albeit covered with ice for more than half of the year. The highest point on the island is the summit of Qalorujoorneq, at topping a wide mountain massif in the southeast, directly above the Kulusuk Airport. Qalorujoorneq has three ridges. Its southeastern ridge extends to the southeastern promontory on the island, with two distinct peaks: Saajat at and Kangeq at.
Lakes
There is one larger lake on the island, Qalorujoornep Tasia, located in a post-glacial cirque in the heart of the island directly west of the western wall of Qalorujoorneq. Its northern shore is situated just shy of the shallow saddle in the northwestern ridge of the mountain, directly above the airport. During the brief summer a stream flows to the west, to then turn north through the depression in the center of the island, to join the second-largest lake on the island, serving as a water reservoir for the settlement. The reservoir empties into a smaller pond on the edge of the village just south of the coastal scarp. The outflow from the reservoir leads to the west, through a series of smaller interior lakes, draining into Tiivtingaleq bay. All lakes and streams are frozen during winter.
