Fort Atkinson State Historical Park
🏆 Official Guide: Fort Atkinson State Historical Park — Site of the first U.S. military post west of the Missouri River (1820–1827) in Fort Calhoun, Nebraska — where Lewis and Clark held their first council with the Oto and Missouria tribes in 1804 — featuring the reconstructed fort, the Harold W. Andersen Visitor Center with museum exhibits, living history demonstrations (blacksmithing, carpentry, fur trading), self-guided walking trails along Missouri River bluffs, and views of historic “Council Bluff.”
Fort Atkinson State Historical Park stands on one of the most historically significant sites in American westward expansion. In 1804, Lewis and Clark identified this bluff overlooking the Missouri River — which they named “Council Bluff” — as the ideal location for a military outpost. By 1820, the fort became the first U.S. Army post west of the Missouri, housing 1,200 soldiers — nearly one-quarter of the entire standing U.S. Army.

Frequently Asked Questions
Is the fort original or reconstructed?
The fort was abandoned in 1827 and the original structures deteriorated. The current fort is a reconstruction built by the Nebraska Game and Parks Commission during the 1980s and 1990s, based on historical records and archaeological evidence.
What is the Lewis and Clark connection?
In 1804, the Lewis and Clark Expedition identified this bluff as “Council Bluff” — the site of their first formal council with the Oto and Missouria tribes. They recommended it as an ideal location for a military fort, which was established 16 years later in 1820.
