Various Native American tribes had lived in the land that became Omaha, including since the 17th century, the Omaha and Ponca, Dhegian-Siouan-language people who had originated in the lower Ohio River valley and migrated west by the early 17th century; Pawnee, Otoe, Missouri, and Ioway. The word Omaha (actually Umoⁿhoⁿ or Umaⁿhaⁿ) means "Dwellers on the bluff". In 1804 the Lewis and Clark Expedition passed the riverbanks where the city of Omaha would be built. Between July 30 and August 3, 1804, members of the expedition, including Meriwether Lewis and William Clark, met with Oto and Missouria tribal leaders at the Council Bluff at a point about 20 miles (32 kilometers) north of present-day Omaha. Immediately south of that area, Americans built several fur trading outposts in succeeding years, including Fort Lisa in 1812; Fort Atkinson in 1819; Cabanné's Trading Post, built in 1822, and Fontenelle's Post in 1823, in what became Bellevue.
