How long was the expedition in North Dakota?

The expedition spent 214 days in North Dakota on two separate visits. The group spent 146 days on its outbound trip in October of 1804, when it set up a winter camp near Washburn. The second visit was on its return from the Pacific. The expedition stopped again in August of 1806, which was when Sakakawea was returned to her home. One quarter of the expedition was spent in what is now called North Dakota. 

Were Lewis and Clark the first white men in North Dakota? 

Fur traders and trappers from Canada and other areas had been coming to the area for around 60 years prior to Lewis and Clark’s arrival. The Knife River Indian Villages was a large trading Mecca and in 1803 more people lived in the villages than in St. Louis.

What did they eat?

Expedition members carried some food supplies with them like pork, flour, dried soup, lard and liquor. While in North Dakota, the Corps found bountiful game like buffalo, elk, deer and antelope - the men were documented as sometimes eating up to nine pounds of meat per day! They also obtained food like corn, squash and beans from the Mandan and Hidatsa Indians.

Why is the winter camp located in Washburn, named Fort Mandan?

The camp is located in present day Washburn, North Dakota, but the fort is named after the Mandan Indians who were known for being peaceful and hospitable.

Where did the Mandan and Hidatsa peoples live?

The Mandan and Hidatsa’s village site remains are still easily visible at the Knife River Indian Villages National Historic Site, near Stanton, about 30 miles west of Washburn.

What sort of animals were in North Dakota in 1805?

Lewis and Clark found hundreds of thousands of buffalo, elk, deer (including mule deer), antelope, prairie dogs and beaver in North Dakota. Near Bismarck, men of the expedition wounded their first grizzly bear, but it escaped before they could find it.

Were there any injuries during the expedition?

Captain Meriwether Lewis was accidentally shot near present-day Williston on August 11, 1806. He was shot by one of the crew members (Pierre Cruzatte) during a hunting expedition. Lewis was dressed in buckskins at the time and Cruzatte was known to be very nearsighted. Lewis was shot in the buttock, and no arteries or bones were severed. Clark wrote that Lewis was fully healed by September.
