Park Forest meteorites showered over populated areas, and a number of homes, vehicles, and man-made objects were impacted. Park Forest is a famous "hammer" meteorite that is a must have for any collector. (see the Meteoritical Bulletin entry below)
This display contains a small sample micromount of Park Forest meteorite. The specimen is housed in an acrylic gemjar, which is then placed inside a Riker box display. The display has a print of the Park Forest bolide as it appeared in the sky. The specimen inside can be removed and handled, if desired. This display would make a fine outreach or teaching prop, and it would look great in the home or office.
