Aboriginal Workman Not Revealed In Artifacts Found On Silverbell Road
Imbedded in caliche and gravel that apparently had been undisturbed for hundreds of years, two fragments of a leaden spear-shaft were found at the third lime kiln on the Silverbell road, seven and a half miles from Stone avenue and Congress street by university scientists yesterday.
In 1924, Charles Manier and his father stopped by a limekiln on Silverbell Road in Tucson, Arizona on a weekend drive. While investigating the ruins, Mr. Manier noticed a large piece of metal sticking out of the ground. This discovery would lead to one of the greatest archeological controversies in the twentieth century—a pre-Columbian Roman-Jewish colony with ties to the Toltecs and possibly, their empire in Tollan, Mexico.
