Hunting on the Nodaway
Heading home, the supply of meat spoils, and the expedition must stop above the Nodaway River to hunt. They get two deer and discover that the pawpaw fruits are nearly ripe. Clark compares the bark of the coyote with that of the common small cur dog.
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.

Over the Bitterroots
11 September–22 September 1805
On 11 September 1805, the expedition leaves Travelers’ Rest and follows a trail high above Lolo Creek in Montana. After passing some hot springs, they follow a trail to the Bitterroot divide at Packer Meadows.
They briefly follow the Lochsa River, but due to its steep canyons, they must climb to the ridges high above. It then commences snowing and there is virtually no game to be had. At one point, Clark writes “I have been wet and as cold in every part as I ever was in my life”.
The travelers subsist on portable soup, tallow melted from candles, and their own precious horses. Clark and a small party scout ahead eventually reaching two Nez Perce villages at Weippe Prairie. They are welcomed and given food, much of which is sent back to Lewis with the main party.
The expedition moves down to the Clearwater River where a camp is established to build canoes. Unfortunately, most of the men are too sick to help.

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.

Hugh McNeal
Private
Lewis wrote that “McNeal had exultingly stood with a foot on each side of this little rivulet and thanked his god that he had lived to bestride the mighty & heretofore deemed endless Missouri.”
Jean-Baptiste Lepage
Private
At the age of 43, Lepage was the oldest member of the expedition. He was a French-Canadian trapper and had lived among the Mandan prior to the expedition. His most embarrassing moment may have been losing the pack horse with Lewis’s winter clothing.
Charles Floyd
Sergeant
Floyd began his journal on 14 May, the day of the expedition’s departure from Camp Dubois. On August 18th Floyd wrote his last entry. Shortly after noon on the 20th, Charles Floyd died “with a great deal of composure.”

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.

Tools and Techniques
Native American Nations
The Lewis and Clark Expedition benefited from the Indians’ knowledge and support. Maps, route information, food, horses, open-handed friendship—all gave the Corps of Discovery the edge that spelled the difference between success and failure.
Medicine on the Trail
From major crisis such as the death of Sgt. Floyd, Lewis’s gunshot wound, and the illness of Sacagawea to minor events such as sexually transmitted diseases, mosquito-born illnesses, and deep cuts, the medical aspects of the Lewis and Clark Expedition provide an interesting topic of study.
The Fur Trade
Given President Jefferson’s directive to establish commerce, the captains worked extensively within a long-established network of North American fur trade. Part of their mission was to help establish the United States of America’s position within that industry.
The Trail
Starting with its genesis in Jefferson’s Monticello, Lewis’s training and preparations in Philadelphia, and the barge’s excursion down the Ohio River, the route they took, often called the Lewis and Clark Trail, crosses the continent weaving an epic tale of western exploration treasured by many today.

Synopsis of the Expedition

Legacies
Legacy is a very slippery sort of term. If we could erase our myth concepts of Lewis and Clark … it might reawaken something really extraordinary in our national consciousness.
Trail Diplomacy
Lewis and Clark left behind among many Indians a legacy of nonviolent contact. Those who came later enjoyed that legacy and too often betrayed it.
The Boats
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.

People
The success of the Lewis and Clark Expedition was due to its many members and the people they met, including politicians, Eastern gentleman scientists, traders, and the many people already living in the American west.
Horse Travel
To cross the Rocky Mountains, the Lewis and Clark Expedition needed horses and the skills to manage them. Despite their seemingly constant struggle to find missing and stolen horses, as a kind of calvary unit, they left hoof prints on approximately 1,500 miles of western terrain.
A Military Corps
Throughout the expedition the soldiers were expected to conform to the rules and routines of the frontier soldier of 1803.
Scientific Explorations
Their work in the emerging fields of botany, ethnography, geography, geology, and zoology are now considered classics of early American scientific literature.
Related Explorers
Lewis and Clark were among several significant explorers of North America both before and after the expedition.
Louisiana’s Purchase
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.
The Arts
Because of the literate journalists, historians and visual artists can tell the Expedition’s story. When they celebrated with song and dance, we too can share in the experience.
Hunting and Fishing
Although hunting and fishing were often considered a ‘gentleman’s sport’ especially in Europe, hunting and fishing for Native Americans and Americans alike were a matter of survival. The success of the Lewis and Clark Expedition depended on the success of its hunters.
