The Ohio House and Senate have approved a bill declaring a two-thousand year old pipe, carved in the shape of a person, as Ohio's official state artifact. The Adena Pipe was excavated in 1901 from a mound in Chillicothe, believed to have been built by members of the Adena Native-American tribe. Democratic State Senator Charleta Tavares of Columbus supported the declaration.
Students at the Columbus School for Girls have been campaigning since 2009 for the Adena Pipe to be honored.
