Igtuk, the boomer, is the source of mysterious booming sounds heard in the Canadian mountains. His place of residence is unknown. Our knowledge of this creature was related by the Iglulik Inuit mystic Anarqâq. Igtuk was not specified to be one of Anarqâq’s helping spirits, and he is probably hostile to humans.
Igtuk resembles no other living thing. His arms and legs are on the back of his body, while his single large eye is level with his arms, and his ears are in line with his eye. His nose is inside his cavernous mouth, and there is a tuft of thick hair on his chin. The booming for which he is known is produced when Igtuk moves his jaws.
