The stone shelter was built by Duse, Andersson and Grunden in February 1903, when they had started to resign to the fact that they would have to winter there. For nine months it was their home. Stone walls one meter thick and roughly a meter and a half high were built from flat rocks using sand, and probably guano, as mortar. The sled was placed on top of the structure as a roof beam, and the tent cloth was hanged from it on the inside of the structure, offering some resemblance of cover from snow and wind. In November 1903 just before the ices were breaking, they re-started their trek towards Snow Hill Island.
