At milepost 251.1 a small pull-off leads to a grassy, wooded clearing marked by a large CHICKASAW COUNCIL HOUSE sign and an interpretive panel. This is the site of Pontatock, capital of the Chickasaw Nation in the 1820s, where chiefs and headmen gathered to sign treaties and to establish laws and policies for the nation. The sign notes, in neutral terms, that two or three thousand Indians camped nearby each summer. There is no preserved or reconstructed council house here, and no visible archaeological structure to walk through, so the experience is subtle and depends largely on reading the panel and imagining the scene. Picnic tables sit near the clearing.
