Kiamichi
The Kiamichi River rises in the forested Ouachita country and flows southwest to the Red River. Its valley provides a passage between the mountains and the lowlands, with tributaries descending from wooded ridges. Caddo communities used the river corridor, and a mound center stood across the Red River near its mouth. Early French visitors knew the waterway, and in 1805 John Sibley recorded its name while describing the upper Red River.
