[1] Administratively it marks the boundary between the Avannaata municipality and the Northeast Greenland National Park.

The fjord and its glacier are named after German cartographer August Heinrich Petermann.

In several places along the fjord, tongues of the glacier shoot down between the mountains, but at no point here is the production of ice-mountains apparent.

[3]Petermann Fjord stretches roughly from southeast to northwest for about 110 km.

It is a long and broad fjord lined with precipitous cliffs topped by glaciated plateaux.
