The Lewis and Clark Expedition, also known as the Corps of Discovery Expedition, was the United States expedition to cross the newly acquired western portion of the country after the Louisiana Purchase. The Corps of Discovery was a select group of U.S. Army and civilian volunteers under the command of Captain Meriwether Lewis and his close friend Second Lieutenant William Clark. Clark and 30 members set out from Camp Dubois, Illinois, on May 14, 1804, met Lewis and ten other members of the group in St. Charles, Missouri, then went up the Missouri River. The expedition crossed the Continental Divide of the Americas near the Lemhi Pass, eventually coming to the Columbia River, and the Pacific Ocean in 1805. The return voyage began on March 23, 1806, at Fort Clatsop, Oregon, and ended on September 23 of the same year.
Council Bluffs is a city in and the county seat of Pottawattamie County, Iowa, United States. It is the most populous city in Southwest Iowa, as well as the third largest and a primary city of the Omaha-Council Bluffs Metropolitan Area. It is located on the east bank of the Missouri River, across from Omaha, Nebraska. Until about 1853 Council Bluffs was known as Kanesville. Kanesville was the historic starting point of the Mormon Trail. Kanesville is also the northernmost anchor town of the other emigrant trails because there was a steam-powered boat which ferried the settlers' wagons and cattle across the Missouri River. In 1869, the first transcontinental railroad to California was connected to the existing U.S. rail network at Council Bluffs.

The Corps of Discovery was a specially established unit of the United States Army which formed the nucleus of the Lewis and Clark Expedition that took place between May 1804 and September 1806. The Corps was led jointly by Captain Meriwether Lewis and Second Lieutenant William Clark. Commissioned by President Thomas Jefferson, the Corps' objectives were scientific and commercial – to study the area's plants, animal life, and geography, and to learn how the Louisiana Purchase could be exploited economically. Aside from its military composition, the Corps' additional personnel included scouts, boatmen, and civilians.

Iowa is in the tallgrass prairie of the North American Great Plains, historically inhabited by speakers of Siouan languages. The area of Sioux City, Iowa was inhabited by Yankton Sioux when it was first reached by Spanish and French furtrappers in the 18th century. In 1803, during the presidency of Thomas Jefferson, France sold a vast portion of central North America to the United States of America. This "Louisiana Purchase" was largely unexplored by white settlers. Jefferson sent out the Corps of Discovery, under Lewis and Clark, to scientifically document the territory. In 1804 the Lewis and Clark expedition traveled up the Missouri and set-up camp near what would become Sioux City, Iowa. On August 20, a member of the expedition, Sgt. Charles Floyd died of "bilous colic" and was buried on a bluff overlooking the river. At the time of Lewis and Clark, the Omaha tribe of Native Americans were present just downstream from this region, and the Yankton Sioux were upstream. William Thompson established a trading post near Floyd's Bluff in 1848, and had early ambitions for founding a city. However, Thompson's hopes were never realized; settlers further upriver, between the Floyd and Big Sioux rivers, met with more success.
