Project 10073 Record Card — Gary, Minnesota, September 1962

This document details the investigation of a rock sample found in Gary, Minnesota, in September 1962. A civilian resident reported that the object appeared in his yard, and he suspected it might be associated with satellite decay, noting the timing coincided with reports of Russian Sputnik pieces falling in Wisconsin. The sample was forwarded to Wright-Patterson Air Force Base for identification. The object was assigned control number 3-146 and subjected to chemical and physical examination by the Aeronautical Systems Division (ASD). The final analysis, dated February 8, 1963, concluded that the sample was terrestrial in origin and identified it as slag, which is common in regions of past glacial activity. The report confirms that the object was not related to any extraterrestrial or satellite-related phenomena.
