From "Meteorites Found in Pennsylvania" by Ralph W. Stone and Eileen M. Starr:
The almost identical composition of the Mt. Joy, New Baltimore, and Pittsburgh meteorites and the fact that the three localities are practically in a straight line suggest that these may be parts of a larger body which was disrupted as it passed through the earth’s atmosphere. The fact that the New Baltimore locality is 10 miles south of a line from the locality near Gettysburg to the site south of Pittsburgh and that these places are 150 miles apart does not seem incompatible with the idea of a single source when it is known that the average velocity of meteors passing through our atmosphere is computed to be between 20 and 30 miles a second and the height of passage above the earth may be several miles. Furthermore, as none of these was seen to fall, and the last was discovered 72 years after the first, all may have been buried in the soil for hundreds of years. |
