Lewis and Clark take the keelboat down the Ohio River. Near this date, they pass the Wabash River and perhaps stay at Old Shawneetown in present Illinois.

When the waters of the Ohio are high, the banks of the Wabash are overflowed for several miles up: it is about 400 yards wide at its mouth, and enters the Ohio at nearly right angles.

The Expedition continues down the Columbia. They see large river bottoms, islands, Indian villages, and a hill with graves. They camp on a narrow beach below a basalt cliff presently named Little Cape Horn. The fleas are bothersome.

We came 27 Miles this day & encamped on the North side of the River, under a Clift of Rocks.
