A group of five meteorite shallow craters located about ten miles southwest of Odessa. The largest is approximately 165 meters wide -- second largest crater in the US.

The craters were produced by the Odessa (iron) meteorite, a coarse octahedrite classified as a member of the main group of IAB meteorites (IAB-MG). Since 1922 1.6 tons of meteoritical material has been recovered. The silicates and several other familiar minerals listed here are, in the main, constituents of the original meteorite. Several IAB iron meteorites, including Odessa (iron), contain 'silicate' inclusions which contain olivine, orthopyroxene, plagioclase and other minor minerals. At least two of the minerals listed here (hibbingite and lawrencite) were produced by terrestrial weathering of the original iron meteorite.

The proper name for the meteorite associated with the Odessa Craters is 'Odessa (iron)' as the 'Odessa' meteorite refers to fragments of the Grossliebenthal meteorite which fell in the Odessa Province of Ukraine.
