[1] The fjord was first sighted in June 1917 by Knud Rasmussen and Lauge Koch from the top of Thule Mountain which rises in Hazenland above the shore of De Long Fjord.

Rasmussen named it after Danish mineralogist Ove Balthasar Bøggild (1872-1956), a member of the Scientific Committee of the 1916-1918 Second Thule Expedition.

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

To the south lies the Hans Tausen Ice Cap from which some glaciers flow into its southern shore.

The fjord is roughly oriented in an east / west direction and is over 20 km (12 mi) in length.
