Historian Mark Walczynski was on hand to accept the donation. Wasting little time, he was able to identify certain artifacts as side notches of the archaic period (8,000 to 1,000 B.C.) and durst points from inhabitants who were hunters and gatherers.
Other tools were identified from the Woodland period (500 B.C. to 1100) into the Mississippian period (800 to 1600) as native inhabitants transitioned from thousands of years as hunters and gatherers to a more agricultural society — and adapted as European settlers entered the area and started trading.
One item Walczynski referred to as a "Fox River point," noting it was "very rare."
Geologist and volunteer Joe Jakupcak said most of the tools are made of flint, and were likely found in fields where farmers tilled up the soil and brought them to surface. He acknowledged finding these kinds of tools is harder today because farmers don't till these areas of the park.
