Lewis and Clark Expedition
President Jefferson sent Meriwether Lewis and William Clark to explore the Missouri River and discover a stream leading from its headwaters to the Pacific which would afford the best water route for developing commerce.

Lewis and Clark set out up the Missouri on May 14, 1804, reached the mouth of the Osage on June 1, passed the mouth of the Nodaway on July 8 and the Nishnabotna on July 14, and began poling and sailing along the southwestern border of Iowa on July 18.

On July 29 they encamped on Iowa soil a short distance above the mouth of the Boyer River. The next day they nosed their boats into the Nebraska shore at a place they called "Council Bluff" to await the arrival of the Missouri and Oto Indians.

When the Indians arrived on August 3, Lewis and Clark told them of their mission up the Missouri and advised them on "how they were to conduct themselves". They presented the chiefs with medals, a "Cannister of Powder and a Bottle of Whiskey". The colorful council on the Missouri above present-day Omaha is commemorated in the town of Council Bluffs, Iowa.
