A lunchtime post of a remarkable prehistoric artifact. Attached is a photograph of an Adena leaf-shaped bifacial blade, of milky blue Flint Ridge chalcedony obtained in Ohio. This form of tool is one of the signature artifacts of the Adena mound-building culture. Even more interesting this blade was found on a site on the upper Chesapeake Bay region of Maryland, a result of clear but still poorly understood contact between the Ohio heartland and Adena-related sites in the east.
