Timeline of the Lewis and Clark Expedition

There were 33 people, including 29 participants in training at the 1803–1804 Camp Dubois winter staging area in Illinois Territory, near present day Hartford, Illinois. They left on May 14, 1804, and met up with Lewis in St. Charles, Missouri, a short time later; the corps followed the Missouri River westward. Soon they passed La Charrette, the last Euro-American settlement on the Missouri River.

The expedition followed the Missouri through what is now Kansas City, Missouri, and Omaha, Nebraska. On August 20, 1804, Sergeant Charles Floyd died, apparently from acute appendicitis. He was buried at Floyd's Bluff, in what is now Sioux City, Iowa. During the final week of August, Lewis and Clark reached the edge of the Great Plains, a place abounding with elk, deer, bison, and beavers.

The Lewis and Clark Expedition established relations with two dozen indigenous nations, without whose help the expedition would have starved to death or become hopelessly lost in the Rocky Mountains
The Americans and the Lakota nation (whom the Americans called Sioux or "Teton-wan Sioux") had problems when they met, and there was a concern the two sides might fight. According to Harry W. Fritz, "All earlier Missouri River travelers had warned of this powerful and aggressive tribe, determined to block free trade on the river. ... The Sioux were also expecting a retaliatory raid from the Omaha Indians, to the south. A recent Sioux raid had killed 75 Omaha men, burned 40 lodges, and taken four dozen prisoners.
One of their horses disappeared, and they believed the Sioux were responsible. Afterward, the two sides met and there was a disagreement, and the Sioux asked the men to stay or to give more gifts instead before being allowed to pass through their territory. They came close to fighting several times, and both sides finally backed down and the expedition continued on to Arikara territory. Clark wrote they were "warlike" and were the "vilest miscreants of the savage race."

Reconstruction of Fort Mandan, Lewis & Clark Memorial Park, North Dakota.

In the winter of 1804–05, the party built Fort Mandan, near present-day Washburn, North Dakota. One chief asked Lewis and Clark to provide a boat for passage through their national territory. As tensions increased, Lewis and Clark prepared to fight, but the two sides fell back in the end. The Americans quickly continued westward (upriver), and camped for the winter in the Mandan nation's territory. Here they met a French-Canadian fur trapper named Toussaint Charbonneau, and his young Shoshone wife Sacagawea, who helped translate.

They followed the Missouri to its headwaters, and over the Continental Divide at Lemhi Pass. In canoes, they descended the mountains by the Clearwater River, the Snake River, and the Columbia River, past Celilo Falls and past what is now Portland, Oregon at the meeting of the Willamette and Columbia Rivers. Lewis used William Robert Broughton's 1792 notes and maps to find the stratovolcano mountain for navigation.

The expedition faced its second bitter winter, and voted on whether to camp on the south side of the Columbia river (modern Astoria, Oregon), building Fort Clatsop. Because Sacagawea and Clark's slave York were both allowed to participate in the vote, it may have been the first time in American history where a woman and a slave were allowed to vote. The Corps turned home on March 23, 1806, using canoes, and later by land.

On July 3, before crossing the Continental Divide, the Corps split into two teams so Lewis could explore the Marias River. Lewis' group of four met some men from the Blackfeet nation. During the night, the Blackfeet tried to steal their weapons. In the struggle, the soldiers killed two Blackfeet men. Lewis, Drouillard, and the Field brothers, fled over 100 miles (160 km) in a day before they camped again.
