[1] Wulff Land was named after Swedish botanist and Arctic explorer Thorild Wulff (1867–1917), who went with Knud Rasmussen on the Second Thule Expedition and died from fatigue near Cape Agassiz in southern Peabody Bay.

[2] The Wulff Land peninsula is a barren and inhospitable place.

Unlike Peary Land to the NE, no remains of human habitation have been found.

Nares Land lies to the east, across the Victoria Fjord and Stephenson Island to the northeast.

[3] To the south the peninsula is attached to the mainland and its ice cap.
