In May 1907 Mylius-Erichsen entered the unknown Danmark Fjord with his three-dogsled exploration team, deeming it would be leading him to the Navy Cliff and the postulated Peary Channel, which in fact did not exist. The team, which included cartographer Niels Peter Høeg Hagen and dogsled expert Jørgen Brønlund, travelled southwestwards until the head of the fjord and, becoming aware that it was a dead end, they backtracked to the northeast.
By the end of May Mylius-Erichsen's team was back again at the mouth of the fjord. As they met Johan Peter Koch's northern team at Cape Rigsdagen, already on their way back from Cape Bridgman, Mylius-Erichsen realized that they had wasted precious time and provisions by entering the long unexplored fjord. The delay would eventually lead the three men to their death as they pressed westward along the southern shore of Independence Fjord instead of returning to the ship.[2]
