On April 12, 2018, Pierre Stromberg was contacted by the family of one of the co-discoverers of the artifact. Offered an opportunity to physically inspect the artifact, Stromberg accepted and also arranged for the artifact to be inspected by a geologist from the University of Washington Earth and Space Science department.
Investigating the origins of the Coso Artifact revealed that mining operations were conducted in the area of discovery early in the 20th century.
The Coso Artifact was indeed a remarkable device. It was a 1920s-era Champion spark plug that probably powered a Ford engine, possibly modified to serve mining operations in the Coso mountain range of California
