Project 10073 Record Card — Greens Fork, Indiana, April 8, 1958

This document file chronicles a series of exchanges between a civilian resident of Indiana and the Air Intelligence Office at Wright-Patterson Air Force Base during the spring of 1958. The civilian submitted a rock specimen, which they believed to be a part of a meteor, for military evaluation. The correspondence includes several letters from the civilian, who expressed a persistent interest in meteorites, even suggesting that their collection might be radioactive or related to a 'pot of gold' found in the area. The civilian also provided a newspaper clipping about local gold panning in Morgan County, Indiana, to support their claims. The Air Force, under Project 10073, initially responded with a standard acknowledgement, noting that they were not interested in meteorites unless they contained a significant metal content. Despite the civilian's continued attempts to provide more samples and sketches of 'strike orbits,' the military eventually conducted a formal analysis of the submitted specimen. The official disposition form, dated April 23, 1958, concluded that the specimen was not a meteorite. Instead, the analysis identified the object as a glacial boulder composed of typical basaltic material, likely transported to its location by Ice Age glaciers. The report noted that the rock lacked the characteristic signs of aerodynamic heating, such as pitting and surface fusion, which would be present on a true meteorite. The military concluded that the specimen was of terrestrial origin and that further laboratory examination was not warranted, effectively closing the inquiry.
