Metbase description: Show/Hide
Knives of iron with bone handles were given to Capt. John Ross in 1818 by the Esquimos of Prince Regent's Bay, John Ross, Voyage of Discovery in Baffin's Bay, London, 1819, p.102-118. Three large masses, weighing respectively about 59 tons, 3 tons, and 896lb and named "The Tent" or Ahnighito, "The Woman," and "The Dog", were shown to Lieut. R.E.Peary, by whom they were later transported to New York, R.E.Peary, Northward over the Great Ice, London, 1898, 2, p.145, 553, 600, M.H.Hey, Cat. Met., 1966, p.87. The weight of Ahnighito was long in doubt but is now known to be 31 metric tons, B.Mason, Meteorites, Wiley, 1962, p.27, M.H.Hey [loc. cit.]. The Ni content varies in different parts of the masses, 7.34 to 7.86% Ni, V.M.Goldschmidt, Proc. Roy. Inst. Gt. Britain, 1929, 26, p.73, V.M.Goldschmidt, Die Naturwiss., 1930, 18, p.999 (M.A.5-7), M.H.Hey [loc. cit.]. Another mass of 3.5 tons was found by Esquimos on a small peninsula called Savik in the Prince Regent Bay; it was removed to Copenhagen, Univ. Min. Geol. Mus., in 1925; description, O.B.Boggild, Meddel. Gronland, 1927, 74, p.11 (M.A.3-535). The mass of 48kg found in 1955 and reported, F.C.Leonard, Meteoritics, 1965, 1, p.305 (M.A.13-82), as a new mass of Cape York is a distinct fall named Thule, V.F.Buchwald, GCA, 1961, 25, p.95. Three further masses have been reported, one of 7.8kg found at Saveqarfik in 1961 (Savik II) and one of about 15 tons found in 1963 at Agpalilik, V.F.Buchwald, GCA, 1964, 28, p.125. The third mass of 250g was found on Northumberland Island, 77°30'N, 71°W, but is believed to be a transported fragment from the Melville Bay area, V.F.Buchwald, Naturens Verden, 1964, p.33, M.H.Hey [loc. cit.].
