It is off of the northern tip of Greenland, and consists primarily of seabed mud and moraine, an accumulation of unconsolidated debris left behind by glaciers.
In September 2022, Danish researcher René Forsberg, head of geodynamics at the National Space Institute in Denmark, announced that further research had shown Qeqertaq Avannarleq "unequivocally" is not an island, but the top of a grounded iceberg, covered by a layer of soil, pebbles and mud, likely deposited by glaciers in the area.
[3][4] An undisputed candidate, Kaffeklubben Island is classified as permanent, being discovered in 1900 A.D., and being 750 metres (2,460 ft) farther north than Cape Morris Jesup, the northernmost point of mainland Greenland.
Initially, scientists were out to visit Oodaaq, a similar formation discovered in the 1970s that also is among those in contention to be the northernmost point of land.
The realization that scientist had found a new landmass went as follows: when photographs of a landing on Qeqertaq Avannarleq were posted to social media, a group of hobbyist adventurers known as 'island hunters' prompted further investigation.
