to Sir John Ross' discovery that the natives of Greenland used iron knives, Nordenskiöld landed at Fortune Bay on Disko Island to search for the material. The Inuit had told Ross that they got the iron from high on a mountain, at a site where two large boulders lay. One was very hard and could not be broken, but the other was chipped into smaller pieces from which balls of iron were extracted and hammered into flat discs for the knives. Nordenskiöld searched unsuccessfully for the site, until being led by some of the local Inuit to a place called Uivfaq, where large masses of metallic iron were strewn about the area. He assumed that the metal was of meteoric origin, since both contain significant amounts of nickel and both had Widmanstätten patterns. Most scientists at the time believed that no un-oxidized telluric iron existed, and few questioned Nordenskiöld's finding. Gustav Nauckhoff made an expedition to Greenland in 1871. Armed with dynamite and lifting equipment, his expedition collected three large samples of telluric iron, also believing them to be meteoric, per Nordenskiöld's examination, and brought them back to Europe for further study. These samples can be found currently in Sweden, Finland, and Denmark. A 25-ton block now rests outside of the Riksmuseum in Stockholm, a 6.6 ton block outside the Geological Museum in Copenhagen, and a 3-ton block can be found in the Museum of Natural History in Kumpula, Helsinki. Accompanying Nauckhoff in 1871 was K. J. V. Steenstrup. Due to circumstances like the shape of the boulders, which often had sharp corners or jagged edges that are not characteristic of meteorites (which ablate considerably during atmospheric entry), or the fact that many had areas that were encrusted with basalt, Steenstrup disagreed with Nordenskiöld about the origin of the boulders, and set out on an expedition of his own in 1878. In 1879, Steenstrup first identified the type 2 iron, showing that it also contained Widmanstätten structures. Steenstrup later reported what he found: In the autumn of 1879, I made a discovery in connection with this matter, for in an old grave at Ekaluit ... I found 9 pieces of basalt containing round balls and irregular pieces of metallic iron. These pieces were lying together with bone knives, similar to those brought home by Ross, as well as with the usual stone tools ... whereas the 9 pieces of basalt
