A replica of the log fort where the Lewis and Clark expedition spent the winter of 1804-05 on the Missouri River. The nearby interpretive center adds context; check seasonal opening before you go.

The Lewis and Clark Expedition began building Fort Mandan on the Missouri on November 2, 1804, using cottonwood lumber, and wintered there until April 6, 1805. The fort was triangular with high walls; temperatures sometimes fell to about -43 °C (-45 °F). During the winter the captains met Sacagawea there; her son Jean Baptiste was born on February 11, 1805. The fort stood just downriver from the villages of the Mandan and Hidatsa. The precise location of the original is not known for certain and is believed to be under the river.

Today a replica stands near the North Dakota Lewis and Clark Interpretive Center near Washburn. Allow one to two hours for the replica and the visitor center. Hours vary by season, so check before you go, especially outside summer.
