The Cartersville Meteorite
by Dave Gheesling

At about 11:00 p.m local time on March 1, 2009, a meteorite was heard when crashing through the roof of a house in Bartow County, Georgia. An extensive search of the surrounding area has been conducted by the author and several others, but no additional stones have been found, most likely because the terrain does not present favorable recovery conditions.

Impact artifacts remain on the meteorite's surface, including roofing material, wood fibers from impact with the rafter, gypsum from passage through the ceiling and paint from a glancing blow with an interior door. Arrangements are currently being made to classify the stone, which is an ordinary chondrite originating from either the L or LL parent body.

A meticulous search for the missing fragment was also conducted inside the attic and house, but nothing was found as it was almost certainly an air break.
