on coast of Beaufort Sea, W point of entrance to Harrison Bay, Arctic Plain.
Dease and Simpson (Simpson, Thomas, 1843, p. 133) July 26, 1837, reported that "this remarkable point was named Cape Halkett, in compliment to one of the Company's (Hudson's Bay) Directors." Leffingwell (1919, p. 96) gives the Eskimo name as "Ishuk," which he says Vilhjalmur Stefansson spells "Isuk," meaning "end."
