United States · 19th century
Fort Mandan was the name of the encampment which the Lewis and Clark Expedition built for wintering over in 1804–1805. The encampment was located on the Missouri River approximately twelve miles (19 km) from the site of present-day Washburn, North Dakota, which developed later. The precise location is not known for certain. It is believed now to be under the water of the river. A replica of the fort has been constructed near the original site.
