On the Trail

September 24, 1803
Maysville recruit?
Near this date, Lewis likely stops in Maysville, Kentucky near the home of John Colter who served admirably as a private in the expedition and would later become famous for his life as a mountain man. Thomas Rodney describes the town, a boat being built there, and expresses a low opinion of Ohio River settlers.

September 24, 1804
Buffalo Medicine
As the enlisted men and engagés move the boats towards the Lakota Sioux encampments at present Pierre, South Dakota, Pvt. Colter's horse is stolen. The captains smoke with Buffalo Medicine, and a promise is made to return the horse and to meet with the captains tomorrow.

September 24, 1805
Down to the Clearwater
At the Weippe Prairie villages, the enlisted men round up scattered horses, and the entire corps travels down to the Clearwater River. Several men are so sick they can barely stay on their horses. They camp on a small island near present Orofino, Idaho.

September 24, 1806
Dinner with Mr. Chouteau
In St. Louis, the captains have dinner with 'Mr. Chouteau' and then go shopping. They also write letters to President Jefferson and Clark’s brother Jonathan with news of the expedition’s return.
Down the Ohio
31 August–13 November 1803
On 31 August 1803, after months of preparation, Lewis and his crew finally head down the Ohio River. Unfortunately, the water is so low that they must frequently unload and tow the overloaded barge with horses and oxen.
At the request of President Jefferson, Lewis disembarks at Cincinnati and travels overland to gather fossils at Big Bone Lick. He meets the boats, and together they continue to the Falls of the Ohio to pick up William Clark and several new recruits.
The expedition arrives at Fort Massac near the mouth of the Ohio on 11 November. There, they meet George Drouillard and immediately hire him as an interpreter. His first mission is to find the missing army recruits from Fort Southwest Point in Tennessee.

Crossing the Lakotas
9 September–25 Oct 1804
Moving the flotilla of boats up the Missouri in the present states of South and North Dakota, the expedition encounters several nations with limited experience with St. Louis-based traders.
Soon after going around the Big Bend of the Missouri, they meet the Lakota Sioux, and a multi-day encounter goes badly for both peoples. They proceed on to some Arikara villages where they hold a council and invite Too Né (Eagle Feather) to travel with them. He provides useful information and would eventually visit Washington City.
In late October, they reach the Knife River Villages—a complex of Hidatsa and Mandan villages. With winter quickly approaching, they must act fast to establish winter quarters.

Among the Nez Perce
20 September–17 October 1805
Fatigued and physically sick after crossing the Bitterroot Mountains, the expedition is aided by the Nez Perce. With their help, they find a location on the Clearwater River to build five dugout canoes and employ the Nez Perce method of burning out the Ponderosa pine logs.
The Nez Perce agree to take care of the expedition’s horses while they continue to the Pacific Ocean. Two Nez Perce chiefs volunteer to guide them down the Clearwater and Snake to the Columbia. The guides help scout the rapids and introduce the expedition to the various Nez Perce and Palouse bands fishing in the many rapids.
On 16 October 1805, they negotiate the last Snake River rapid and arrive at the Columbia River where many Yakamas and Wanapums are gathered. About two hundred men approach, singing and beating their drums.

The Final Leg
11 August–26 September 1806
While hunting on the Missouri River below present Williston, North Dakota, Lewis is accidentally shot through the flesh of his buttocks. The next day, they catch up to Clark’s party at Reunion Bay. As one united force, they are ready to sprint down the river to St. Louis.
At the Knife River Villages, they drop off the Charbonneau family and pick up Chief Sheheke and interpreter René Jusseaume who will visit Washington City.
The faithful paddlers meet several traders and receive flour, whiskey, woven shirts, and most importantly, news of the United States.
On 23 September 1806, the citizens of St. Louis—having given them up for dead—provide a boisterous welcome. The captains commence writing.

Unloading the Red Pirogue at Camp River Dubois
In the words of artist Steve Ludeman, “I am fascinated with the geology, archeology, natural history, and cultural history of our country.” For years, he has specialized in landscapes and seascapes of the Pacific Northwest, but he also interprets the Eastern Legacy of Lewis and Clark. This is the 1803-04 journey of the Lewis and Clark Expedition from the Eastern seaboard, down the Ohio, up the Mississippi, to their winter camp at River Dubois (Wood River) across from St. Louis. These focus areas combine his love of history and outdoor adventures with a love of painting. For him, the journey of painting is a joyful one.

Starting at Pittsburgh, traveling to the Pacific Ocean, and then returning to St. Louis, the Lewis and Clark Expedition traveled approximately 10,600 miles. Of that, 85%—over 9,000 miles—was by boat. To understand travel in the early 1800 American West is to understand the boats and challenges of river navigation.

The President’s representatives in Paris had bargained successfully with Napoleon’s bureaucrats not only to buy the port of New Orleans, then the keystone of the continent, but also to acquire, at three cents an acre, an area extending from the Mississippi River to . . . where? No one knew until Meriwether Lewis stood at the crest of the Rocky Mountains at a place known today as Lemhi Pass, on 12 August 1805.
