Park Forest meteorite, 4g fragment.jpg

This important modern American fall took place on March 26, 2003, in the suburbs south of Chicago, Cook County, Illinois. A bright bolide was spotted over various parts of the midwest followed by sonic booms in the vicinity of the fall. Residents of the Park Forest community awoke to sounds of explosions as numerous fragments battered area homes, cars and other structures. This meteorite is classified as an L5 ordinary chondrite and the matrix varies from light to dark gray in appearance. This partial slice was cut from a piece found by Roman Jirasek and weighs 4.02 grams. It is an example of the "dark material" lithology and has a trace of fusion crust along one edge.
