![]() Wood gave the Keyes Meteorite its official classification as an L6 chondrite. Even though the museum told NASA about the meteorite having been in three pieces, they agreed that based on excellent fit and continuity of surface features that it is all one meteorite. In the late 1960s NASA became interested in the meteorite, especially regarding comparing it with lunar rock samples and at their request the museum loaned the meteorite to NASA for study. Stovall wrote the first technical history and scientifically acknowledged published description of it in December 1948 in the museum publication “The Museum of the University of Oklahoma Information Series Circular.” The Keyes Meteorite was donated to the Stovall Museum of Science and History where C. ![]() Reassembly of all the large fragments and many of the smaller pieces was possible based on excellent fit of the pieces and continuity of surface features. Museum scientists confirmed it was indeed a meteorite that the student found. The student and his grandfather (who was a county agent in Cimarron County, Oklahoma) thought it was a meteorite, so on July 23, 1940, a fragment was brought to the Stovall Museum of Science and History (now the Sam Noble Museum) for confirmation of the meteorite identification via chemical and physical examination. The total weight of recovered fragments was 142 kg/312 lbs. and 68 kg/150 lbs.) and several smaller fragments (less than a fraction of an ounce each). It was apparently quite old, as it was broken and scattered by the many years plowing and it was in three large fragments (23 kg/50 lbs., 27 kg/60 lbs. The next year while plowing, recalling the incident, he immediately stopped when he heard the metallic hit and discovered what he thought was a meteorite. As soon as he realized this, he stopped and walked back to investigate but could not find what the plow had struck. It was not until he was about 100 yards down the field that he realized that the hit made a metallic sound and that he might have hit a meteorite. The Keyes Meteorite was originally discovered in the summer of 1939 by a student of the University of Oklahoma when his plow hit the meteorite while disking his grandfather’s field to prepare for planting wheat.
