Iroquois Legend of a Bridge Spanning the Ohio River Constructed by the Adena. Portsmouth?
Iroquois Book of Rites, 1883
"In Iroquois hydrography, the Ohio--the great river of the ancient Alligewi domain--is the central stream to which all the rivers of the mighty West converge. This stream the emigrants now attempted to cross. They found, according to the native annalist, a rude bridge in a huge grape-vine which trailed its length across the stream. Over this a part of the company passed, and then, unfortunately, the vine broke. The residue, unable to cross, remained on the hither side, and became afterwards the enemies of those who had passed over."
