In 1906 an iron mass was found by a little old boy who tended cattle in the forest 3 km southwest of the village Kitki?j?rvi. 50 years later a larger 15 kg mass was recovered.  The description by Buchwald (1975) covering the first 3 masses (Muonionalusta I, II, and III) provides a broad overview of Muonionalusta's mineralogy. The original meteorite was a fine octahedrite which fragmented before reaching the earth's surface and has since been effected by the reworking of glacial ice of the last ice age. The major constituents kamacite, taenite, troilite, schreibersite, and minor sulfides are, of course, not unexpected in a IVA iron. The several associated weatherates (Akaganeite, Goethite, Lepidocrocite) offer an unusual opportunity to study the effects of long exposure to an unusual and extremely cold environment.
