To the south it is separated from Kongsfjorden by a line from Collinsodden on Mitrahalvøya east to Kapp Guissez.
The English explorer (and later whaler) Jonas Poole entered Krossfjorden in 1610, naming it Close Cove.
A small bay in the southwestern entrance of Krossfjorden, named Cross Road by Poole (1610) and now known as Ebeltofthamna, was the location of the first whaling station in Spitsbergen in 1611.
The remains of a later, semi-permanent station have been found there as well on a long, low arm of the beach between the fjord and a lagoon.
The name originates from the placing of a cross by Poole in 1610 on the side of a hill a mile west of Ebeltofthamna, on which he wrote the day and year of his arrival, as well as who sent him.
