Lewis and Clark take the keelboat down the Ohio River. Near this date, they pass notable landmarks such as Cave in Rock and Hurricane Island near present Elizabethtown, Illinois.

Rock in Cave, and island, channel right side, This is a curious cave, it presents itself to view a little above the level of the surface of the water when high, and close to the bank of the river, on the right side, a little darkened by the shade of some trees which stand before its mouth. It is about 180 feet deep, and its mouth is of a semicircular form, about 80 feet at its base and 25 feet in height. The cave bears the inscriptions of the names of persons who have visited it at different times and the dates, &c.

The Expedition crosses Grays Bay near the mouth of the Columbia River, where high waves force them to stop. Several of the men are seasick. The tides raise and lower the logs on which their baggage is stored—a dangerous situation.
