After 1805
When the Corps passed back through the area in August, 1806, on their return journey home, the fort had burnt to the ground; the reason is unknown. Since that time, the Missouri River has slowly eroded its bank and has shifted to the east, covering up what remained of the charred fort.
A replica stands along the river, 2.5 miles from the intersection of ND 200A and US 83. It is located near the North Dakota Lewis and Clark Interpretive Center, which offers tours and interpretive programs about the significance of the Lewis and Clark Expedition in American and regional history.
