An Old Copper Culture ‘I-D’-style Spearpoint Recovered from Michigan’s Keweenaw Peninsula. Although it resembles Eurasian-style spearpoints, these were cold-hammered and annealed, not smelted. This style is thought to date between 4000-1000 B.C.E. based on similar finds. [640 x 640]

I-D spearpoints are one style of tool and weapon used by the Old Copper Culture (ca. 8000-1000 B.C.E.), who lived around the Great Lakes. They were initially categorized by Warren Wittry between 1950 and 1951. While not as common as I-A or I-B spearpoints, the numbers found so far are still impressive.
