[1][2] The Harder Ford Fault Zone (HFFZ) is a geological structural feature in North Greenland named after the fjord.

[5] Its southern shore forms the northern limit of Amundsen Land.

To the north lies the southern end of Hazenland, Moa Island and Roosevelt Land.

The fjord is roughly oriented in an east / west direction and is over 24 km (15 mi) in length.

Cape Holger Danske is the headland to the south of the mouth of the fjord, in the inner Wild Sound area.
