A native copper fragment mistaken for a meteorite

Summary

In June 1964, a resident of Westfield, Wisconsin, believed she had found a meteorite and sent it to Northwestern for evaluation. The object, flat in shape and notably heavy, was initially described as a piece of a "fallen body." However, the analysis revealed it was not a meteorite, but rather a rare chunk of native copper. This type of copper is more common in northern regions, but it had been carried to the area by glaciers.

The confusion was not uncommon, as native copper can resemble a meteorite in appearance and weight. Although the official report did not classify it as a UFO or unidentified aerial phenomenon, the case illustrates how unusual natural objects can generate interest and misunderstandings. J. Allen Hynek, the project director, responded politely and informatively, highlighting the historical significance of native copper in the region. While not a meteorite, the discovery remained a fascinating conversation piece.
