This reconstruction of the original fort is where the Lewis & Clark expedition spent the winter of 1804-05 as the guests of the Hidatsa and Mandan Indians. Being a military expedition, the party decided to build a fort to house the group and to settle in for the winter. The reconstruction is based on entries and sketches in journals kept by party members. The rooms are redone as they may have been when the expedition was staying there with replica artifacts of the early 19th century.
The reconstruction is built a few miles away from the original site which is now under the waters of the Missouri River which has shifted over time. Docents are on-site to provide a glimpse into the lives of the expedition members during their stay and can also answer questions about their relationship with the local Native Americans and of course Sakakawea (aka Sacagewea).
Only 2 or so miles from the Lewis & Clark Interpretive Center at the intersection of U.S. 83 and State Highway 200A, it's a must-see attraction in this part of the state.
