Umiasussuk is a standalone mountain, a flooded peak, whose trapezoid shape is the landmark of Upernavik town, visible from the Upernavik Airport 7 km (23,000 ft) away, and from the entire eastern and northern coast of Upernavik Island.
Via a small isthmus in the east, the mountain is connected with the remainder of the large Qaarsorsuaq Island.[1] To the north, the Torsuut strait separates the mountain from Atilissuaq Island. To the west, the low Akia Island separates the mountain from Upernavik Island.
