North Dakota, Washburn – Fort Mandan

🏕️ Fort Mandan and Lewis & Clark Country, North Dakota

After our visit to the Lewis & Clark Interpretive Center, we climbed back into the car and drove a very manageable two miles down the road to the Fort Mandan exhibition. In the grand scheme of American road trips — where “just down the road” can sometimes mean an hour and a half of empty freeway — two miles felt almost decadent.

🗺️ A Bit of Background (For Those of Us Who Slept Through History)

For anyone who needs a quick refresher — and I’m not judging, because I certainly did — the Lewis and Clark Expedition was the first overland crossing of the western portion of North America by United States citizens. It was commissioned by President Thomas Jefferson and set off in May 1804, departing from Camp Dubois near the confluence of the Missouri and Mississippi rivers, just north of St. Louis, Missouri.

The expedition’s formal title was the Corps of Discovery, and it was led by Meriwether Lewis and William Clark. Their mission was essentially to explore the territory acquired through the Louisiana Purchase of 1803, find a practical route to the Pacific, and report back on the geography, natural resources, and the indigenous peoples they encountered along the way. Jefferson was enormously curious — some might say obsessive — about what exactly he’d bought. It was, after all, roughly 828,000 square miles of land, acquired from Napoleon’s France for about fifteen million dollars. Quite the bargain, all things considered.

The Corps departed up the Missouri River with around 45 men, including soldiers, French-Canadian boatmen, Clark’s enslaved manservant York, and later the now-famous Shoshone woman Sacagawea and her husband Toussaint Charbonneau. They made their way northwest through what is now Missouri, Kansas, Nebraska, Iowa, South Dakota, and into North Dakota, arriving at the villages of the Mandan and Hidatsa people in late October 1804. It was there they decided to stop and sit out the winter.

🏘️ Not Quite the Wilderness You’d Imagine

Here is where the story gets genuinely interesting, and where I had to quietly revise a few of my assumptions. I had always pictured Lewis and Clark huddled bravely against the howling North Dakotan wilderness, utterly alone apart from a few wolves and an improbable amount of snow. The reality was rather different.

When the Corps arrived in the autumn of 1804, they found themselves in the middle of what was, by any measure, a thriving urban area. There were two Mandan towns — Mitutanka and Ruptare — and three Hidatsa towns: Awaxawi, Awatixa, and Big Hidatsa. Together, these five settlements had a combined population that exceeded that of St. Louis, which at the time was one of the largest cities in the United States. Lewis and Clark had not arrived at the edge of the known world. They had, rather unexpectedly, arrived in a city.

The Mandan people had been living along the upper Missouri River for centuries. They were sophisticated agriculturalists who grew maize, beans, squash, and sunflowers, and they were experienced traders whose villages served as a major hub on the northern plains trading network. People came from hundreds of miles away — Lakota, Assiniboine, Crow, and others — to trade at these villages. The Hidatsa, their neighbours, were similarly well-organised and economically active. These were not isolated communities scraping by. They had systems, commerce, politics, and culture that were every bit as complex as anything the Corps had come from back east.

So for Lewis and Clark, the winter at Fort Mandan was not really about surviving in the wilderness at all. It was about surviving in an urban area. They had to get along with their neighbours, negotiate for food and supplies, handle diplomatic sensitivities with considerable care, and try to make sense of cultures that were entirely foreign to them. It was, in other words, rather like moving to a new city and hoping you don’t annoy everyone before spring.

🏗️ Building Fort Mandan

The Corps built their winter quarters — which they named Fort Mandan, partly out of respect for their hosts and partly, one suspects, because it sounded better than “Fort We’re Desperately Cold and Would Like to Go Home” — beginning in early November 1804. The fort was a small, triangular structure, roughly A-shaped in plan, sitting on the east bank of the Missouri River near present-day Washburn, North Dakota. It was not a grand military installation. It was a practical shelter, built quickly from the cottonwood trees that lined the riverbanks.

The design was functional rather than elegant: sleeping quarters for the men, some storage rooms, a forge for the expedition’s blacksmith work, and a few communal spaces. It was surrounded by a wooden palisade for basic security, though in truth the greatest threats that winter were not hostile attack but rather the ferocious cold, which regularly dropped to minus forty degrees Fahrenheit, and the very real possibility of scurvy if they couldn’t secure enough food. The forge turned out to be rather important — the Corps traded metal goods and repairs for food with the Mandan and Hidatsa, which kept everyone reasonably happy through the long winter.

They stayed at Fort Mandan from November 1804 until April 1805, when the Missouri River thawed and they could resume their journey westward. It was during this winter that they met and engaged Toussaint Charbonneau as an interpreter, and his wife Sacagawea joined the expedition. She gave birth to her son Jean Baptiste Charbonneau at the fort in February 1805 — which, given the temperature outside, must rank as one of the more extraordinary things that happened there.

The original fort, sadly, did not survive. It burned down in the spring of 1806, shortly after the Corps had already resumed their journey. The exact cause was never definitively established.

🏛️ The Replica and the Visitor Centre

What we visited was a carefully researched replica, and it is worth saying that “replica” in this context is not a word to be taken lightly. The reconstruction was based on the detailed journals kept by Lewis and Clark and several members of their party, who between them recorded the dimensions of the fort, the layout of the rooms, and the materials used in its construction. It is, as far as anyone can establish, authentically reproduced.

We went into the visitor centre first, where we watched a film about the expedition. It was well made and genuinely informative — the kind of thing that manages to convey useful historical context without making you feel you’re sitting through a school assembly. After the film, we were taken on a guided tour of the replica fort itself.

It is a small structure. That’s the first thing you notice. Standing inside it, knowing that around 30-odd men spent five months here through one of the harshest winters on the continent, is a rather sobering experience. The sleeping quarters are modest to the point of being claustrophobic. The storage rooms are small. The forge takes up a meaningful portion of the interior footprint. There is nothing here that wasn’t strictly necessary.
