DescriptionHomestead meteorite.jpg |
English: 20.4 gram partial slice of the historic witnessed fall "Homestead". This is a nice specimen with fusion crust along one edge. This slice was taken from a 450 gram fragment that resided in the American Museum of Natural History for over a century. The fall took place on Friday February 12, 1875 in the small town of Homestead, Iowa. At about 10:30 a brilliant fireball lit up the cold dark sky. The flash was followed by loud rumbling sounds as the meteoroid exploded over the snowy countryside. The first meteorite fragment was found two miles west of Homestead by a woman named Sarah Sherlock. The stone weighed seven pounds and six ounces. The largest mass weighed 74 lbs and was not discovered until spring. It along with a 48 pound mass were buried 2 feet in the ground. In total approximately 227kgs of this attractive L5 brecciated chondrite were discovered. Several of the larger pieces made their way into the collection of the State University of Iowa while many others were distributed to museums worldwide. |
