Project 10073 Record Card and Correspondence Regarding Native Copper Specimen

This document file contains a Project 10073 record card and associated correspondence regarding a civilian report of a suspected meteorite found in Westfield, Wisconsin. In June 1964, a resident contacted the Chicago Tribune regarding a metallic object they had discovered, which they believed to be a 'fallen meteor.' The Chicago Tribune directed the resident to the Department of the Air Force at the Pentagon. The resident subsequently sent a description and a small sample of the object to the authorities, describing it as a 'flat-splash shape' weighing approximately 8 pounds. The specimen was forwarded to J. Allen Hynek at Northwestern University for evaluation. In a letter dated August 3, 1964, Dr. Hynek informed the resident that the object was not a meteorite. Instead, he identified it as a rare example of native copper for that region, explaining that such deposits were likely transported to the area by glacial activity. The case was closed with the conclusion that the object was native copper, and the resident was encouraged to keep it as a 'conversation piece.'
