The Geologfjord is part of the Kaiser Franz Joseph Fjord complex.[2]
It is a narrow and winding fjord located between mountains rising up to 2,100 metres (6,900 ft) on both sides, with cliffs displaying beautifully colored strata. It runs roughly in a NW /SE direction with Andrée Land to the west and Strindberg Land to the east. The Nunatak Glacier has its terminus at its head.[2] The smaller Endeløs and Dukke Glacier flow into the fjord from the west.[1]
Bjorne Island, a rocky islet, rises close to the mouth of the fjord, north of Cape Weber, the easternmost end of Andrée Land.[3] To the south the fjord opens into the northern shore of the Kaiser Franz Joseph Fjord and Cape Ovibos is the headland at the eastern side of the entrance.[2]
