Devil's Thumb (Kalaallisut; Greenlandic: Kullorsuaq, Danish: Djævelens Tommelfinger) is a pinnacle-shaped, 546m (1,791feet)[1] mountain in the Avannaata municipality in northwestern Greenland.
Devil's Thumb is located in the central part of Kullorsuaq Island, an island in the northern part of Upernavik Archipelago, in Melville Bay, approximately 3km (02miles) to the north of the Kullorsuaq settlement.[1]
It is a familiar feature for Arctic navigators, similar to the Melville Monument further north, but bigger.[2]
