Lewis and Clark were among several significant explorers of North America both before and after the expedition.
On the Trail
September 11, 1803
Swimming squirrels
Lewis and his small flotilla enter the Long Reach of the Ohio where he sees numerous squirrels swimming across the river. He has his dog, Seaman, capture several and when fried, he finds them fat and tasty. At Louisville, Clark writes a letter to update Lewis on his progress to find an interpreter and recruit young men from Kentucky.
September 11, 1804
Shannon found!
While the enlisted men and engagés move the boats up the Missouri, Pvt. Shannon who has been missing for 22 days, is found. During another hunting incident, the rain wets Sgt. Ordway's gunpowder, and he has a close encounter with a bison bull. Everyone camps near present Rush Creek, South Dakota.
September 11, 1805
The Northern Nez Perce Trail
After looking for stray horses, the expedition heads up the trail that follows Travelers' Rest Creek—present Lolo Creek in Montana. They come across a painted tree and stay at an Indian campsite where the ponderosa bark has been stripped for food.
September 11, 1806
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.

Down the Western Valleys
11 August–10 September 1805
Having reached the end of the navigable Missouri, the captains—aided by Lemhi Shoshone Chief Cameahwait, Sacagawea‘s brother—begin acquiring horses, making pack saddles, and caching supplies they can no longer take with them.
With the help of the Lemhi Shoshones, everything is carried across the Continental Divide. Clark and their new guide they call Toby, scout the Salmon River and find it is not navigable.
After nearly three weeks with the Shoshones, the expedition moves down the Lemhi River valley and heads up the North Fork Salmon River. The captains ignore Toby’s advice to follow the Indian Road, and they are forced to spend a snowy night near the summit of Lost Trail Pass.
Dropping down from Lost Trail Pass, the Flathead Salish give them a warm welcome and sell them some horses. The expedition then proceeds down the Bitterroot River Valley to Travelers’ Rest where they have yet to cross the Bitterroot Mountains.

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.

Reubin Field
Private
Reubin and his brother Joseph (about a year older) were among the best hunters, but Reubin was possibly the better shot. He was, at least, at Camp Dubois on 16 January 1804, when Clark’s men set up a shooting match with some local residents.

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.

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.
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.

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.
Synopsis of the Expedition
by Harry W. Fritz
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.
Other Topics
Other topics include music, holidays, High Potential Historic Sites, and an index of articles from We Proceeded On.
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.
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.
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.
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.
Language
From clichés and colorful sayings of the time to Native American languages, these pages feature the art of language.
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.
Expedition Members
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.
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.
Tools and Techniques
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.
