Lewis and Clark


North Dakota's history is rich with stories from the Lewis and Clark Expedition, also known as the Corps of Discovery. The expedition came through North Dakota twice between 1804 and 1806. In fact, this is where they met and built friendships with such important figures as Sacagawea, Toussaint Charbonneau and Sheheke-Shote. Visitors retracing Lewis and Clark’s footsteps can experience the same landscape and cultures the Corps of Discovery encountered in a number of different ways. 

Lewis & Clark Interpretive Center and Fort Mandan

The North Dakota Lewis & Clark Interpretive Center, near Washburn, stands at the crossroads of culture and commerce on the Northern Plains. When Lewis and Clark arrived at the Mandan and Hidatsa villages in 1804, they simply became the most famous of many people who visited in search of knowledge and trade. Today’s visitors will experience state-of-the-art exhibits, hundreds of period artifacts, and friendly interpreters that tell the story of the Lewis and Clark Expedition like never before.

Just over a mile west of the Interpretive Center is Fort Mandan, a fully furnished, full-size replica of the fort in which the Lewis and Clark Expedition overwintered in 1804-1805. Their stay here was characterized by the hospitality of the Mandan and Hidatsa peoples. In fact, this is where they met and built friendships with such important figures as Sacagawea, Toussaint Charbonneau and Sheheke-Shote. Today visitors can tour the Fort and learn what life was like for the members of the Expedition. 

​​​​​​Cross Ranch State Park

While the Lewis and Clark Expedition did not spend any noted time at this location they did winter just a few miles upstream from this Park. Cross Ranch State Park is located along some of the last free-flowing and undeveloped stretches of the Missouri River.  While exploring Cross Ranch State Park, visitors may find themselves traveling back in time, catching a glimpse of the landscape as it appeared to Native Americans inhabiting the area hundreds of years ago, or hearing the echoes of the Lewis and Clark Expedition making its way to the Pacific coast along the Missouri River.

Fort Abraham Lincoln State Park

As the Lewis and Clark Expedition floated up the Missouri River, Clark noted in his journal the abandoned Indian village. The village referenced in the Expedition journals was the Mandan village, named On-a-Slant (Miti O-pa-e-resh). After prospering on this site for two centuries, a smallpox epidemic hit in 1781 and virtually eliminated the Heart River-region Mandan. The survivors moved north along the Missouri River, eventually joining the Hidatsa near the Knife River. When Lewis and Clark discovered the deserted On-A-Slant Village in late 1804, it was already in an advanced state of decay, for they reported that the remains included fallen heaps of earth, which had covered the houses.

Today On-a-Slant Village is a state historic site and has 6 reconstructed Earthlodges including a large Council Lodge. Tours take you through the village and give visitors an insight into the lives of the Mandan people who once lived at On-a-Slant.
