![]() Morris meteorite is a fragment from the Pine River Meteorite. Later detailed geochemical analysis suggests that the Mt. Morris Stone is a coarsely crystalline sulfide rich stone with forsterite, enstatite, kamacite, schreibersite, troilite, graphite, chromite, daubreelite and chalcopyrite. Waushara County: A stony meteorite massing 1.5 pounds was found near Mt. This proved to be an unusual meteorite for the octahedrite with many silicate inclusions and an “anomalous member of chemical group IA.” The silicate inclusions consist of granular crystalline intergrowths of orthpyroxene, olivine, plagioclase feldspar, troilite and iron nickel metal with accessory chromite, diopside and schreibersite. Waushara County: An iron meteorite with stony inclusions, nicknamed the Pine River Meteorite, was found in 1894 near Saxeville. It also contained about 17% iron-nickel alloys. The meteorite was mostly stony, containing olivine and enstatite. Two fragments with a combined mass of 3.3 pounds were recovered. It came in as a rotating fireball and exploded near ground level. Vernon County: The Claywater Meteorite was observed to fall at 9 A.M. Specimens from this meteorite are on display at the Geology Museum at UW–Madison. Sawn and treated fragments show troilite nodules and lenses. The largest chunks weighed 527 pounds and 413 pounds. At least 13 fragments had been found so far. A detailed search of the area with a metal detector revealed more fragments in 19. Fragments were first found in 1858, with more turning up in 1873. Trenton: A number of large pieces from an iron meteorite have been found in Trenton township, east of West Bend (Washington County). Oshkosh: A 4-ounce fragment of stony meteorite was found on gravel approximately 2 miles NW of Oshkosh (Winnebago County). Several pieces, the largest of which weighs 142 grams, are on display in the Geology Museum at UW–Madison. Mifflin: Named after Mifflin Township in southwest Wisconsin, this stony meteorite fell on April 14, 2010. Samples and a replica are in the Geology Museum at UW–Madison. Kilbourn: A 772-gram stony meteorite fell through a barn roof near Kilbourn (Columbia County) at 5:00 P.M. Chemical analysis gave 89.78% iron and 7.6% nickel with trace amounts of cobalt, phosphorous, silicon, carbon, copper and tin. Troilite was present in nodules and as fracture fillings. Hammond: An iron meteorite massing almost 53 pounds was recovered from a plowed field near Hammond (St. Samples are in the Geology Museum at UW–Madison. The Belmont meteorite is currently in the Geology Museum at UW–Madison.Ĭolby: Two stony meteorites with a combined weight of over 200 pounds fell at 6:15 P.M. It contained mostly bronzite and olivine, but also about 23% iron-nickel alloys. This meteorite is now on display at the Geology Museum at UW–Madison.Īngelica: Approximately 3 miles north of Angelica (Shawano County), a 33-pound iron meteorite was found in 1916 during plowing.īelmont: A stony meteorite weighing 58.28 pounds was found in 1958 near Belmont (Lafayette County). It contained 88.6% iron and 10.6% nickel. Meteorites are called “falls” when the meteorite was observed falling to the ground those recovered later are called “finds.”Īlgoma: A meteorite massing nearly 9 pounds was found during plowing about 4 miles west of Algoma (Kewaunee County). The meteorites ranged in size from less than 1 pound to around 530 pounds. Wisconsin has been hit by at least 13 meteorites since the 1860s. (Adapted from the Minerals of Wisconsin database) ![]()
