The fjord head at approximately is formed by the front of the
Perlerfiup Sermia glacier flowing from the
Greenland ice sheet (). At about one third of its length, the fjord changes direction from westward to northwestward, finally turning sharply to the southwest before
confluence with the northeastern part of Uummannaq Fjord at approximately , due west of
Ukkusissat. The fjord is bounded from the south by the
Ukkusissat Peninsula across its entire length. To the north, it is bound by the mainland of Greenland, the highlands of Akularusersuaq and
Akuliarusikassak, and the mountains of Perlerfiup Nunaa. The coastline is undeveloped−the fjord has only one tributary fjord on its northern bank, the
Qaumarujuk Fjord. == Settlement ==
