LARGE HEMATITE GRINDING
on a construction site in St. Charles County, Missouri
in 2001. Two of the three smaller hematite artifacts
were found in direct contact with the grinding stone.
The Snyders Grooved plummet was found about 50
feet away and may also be directly related. The
largest piece of hematite shows various reduction
processes such as scraping, hammering and grinding.
The other artifact, laying in the center of the grinding
cavity, is a plummet "blank" that was evidently being
pecked, ground and shaped to form a plummet. Notice
the heavy red stain on the surface of the grinding
cavity. This material is red ochre and was caused
from grinding hematite.
