Rules of health
In Philadelphia, Dr. Benjamin Rush writes eleven rules of health on behalf of the upcoming Western Expedition. He recommends purging, wearing flannel, moderation in eating and drinking, and taking good care of the feet.

Bear and deer jerky
Near present Cambridge, Missouri, the winds make steering the boats impossible. Instead of moving forward, they use the day to dry wet cargo. Clark has a bad cold, and the men make bear and deer jerky. The day ends with lively dancing and singing.

Lewis scouts ahead
Lewis sets out to find the Great Falls of the Missouri. His group stops near Vimy Ridge to hunt and fish, where he becomes too ill to continue. He makes a healing decoction from the local black chokecherry trees, and Pvt. Goodrich catches several dozen sauger and goldeye fish. Back at Decision Point, Clark finishes a cache and bleeds Sacagawea, [...]

The camas plant
At Weippe Prairie in present Idaho, Lewis describes the camas plant including how the Nez Perce People harvest and cook its bulbs. Game is scarce, and the hunters are directed to take longer, overnight excursions.
Eastern Beginnings
10 January–30 August 1803
The Lewis and Clark Expedition ostensibly began in February 1801 when President Thomas Jefferson wrote a letter to Army commander General James Wilkinson requesting that Lieutenant Meriwether Lewis become the President’s personal secretary. Exploration of North America’s western half had long been a goal of the president, and now he had a young protégé who might lead such an expedition.
On 18 January 1803, Lewis hand-delivers to the U.S. Congress the President’s request to fund what would become known as the Lewis and Clark Expedition. The President works in Washington City and Monticello to craft instructions and line up the best talent to assist Lewis. In France, three diplomats negotiate with Napoleon Bonaparte to purchase the Louisiana Territory.
Meriwether receives training, supplies and equipment in Philadelphia and avails himself of armaments and specialized equipment—including a collapsable iron-framed boat—at the Schuylkill and Harpers Ferry arsenals. By July 1803, everything is at Fort Fayette in Pittsburgh. All Lewis needs is a large boat to carry everything down the Ohio. He also needs to know if William Clark will accept his invitation to join him.

Up the Missouri
14 May–20 July 1804
On 14 May 1804—after more than a year of preparation and travel—the boats leave Camp River Dubois and head up the Missouri River. At St. Charles, the two captains, Clark’s slave York, interpreter George Drouillard, eight or nine French engagés, 34 enlisted men, and Lewis’s dog Seaman depart in three boats: the barge and two large pirogues.
Everyone quickly learns of the struggles and hazards of moving up the Missouri with its many sawyers and sandbars. Despite the overloaded boats and several close calls, they safely pass many landmarks made familiar by earlier traders from St. Louis.
Crossing the present state of Missouri and then heading north along the Kansas-Missouri border, they pass the homelands of the Omaha, Kansa, Otoe, and Pawnee. On 21 July, they reach the mouth of the Platte where only a handful of traders had ever continued north towards the Knife River Villages.

Along the Northern Reach
7 April–12 June 1805
At 4 p.m. on 7 April 1805, the permanent party heads their six canoes and two pirogues up the Missouri toward the Rocky Mountain barrier. At the same moment, Corp. Warfington and a small crew accompanied by Too Né’s delegation bound for a meeting with President Jefferson head downriver in the barge.
The Missouri River reaches it most northern position flowing from the Great Falls of the Missouri across present Montana and North Dakota. Moving through this stretch, the expedition passes the Yellowstone, Milk, Poplar, and Musselshell rivers. In the Upper Missouri River Breaks, the journalists describe both “scenes of barrenness and desolation” and “seens of visionary inchantment”.
At the mouth of the Marias, they come to a river they did not expect. They are unsure which fork is the true Missouri. After ten days exploring each, the captains decide to take the left fork.
Lewis scouts ahead to find the Falls of the Missouri that they are expecting. Sacagawea becomes dangerously ill and travels with Clark and the boats until they can go no farther—below present Belt Creek.
If the expedition is to be successful, Sacagawea will need gain her health, and the heavy boats will need to be carted around not one, but several waterfalls on a long and difficult portage.

Roads to the Buffalo
10 June–14 July 1806
With the acquisition of horses, Native Nations crossing the Rocky Mountains to hunt for bison became more common. Two of their trails are used by the captains—in separate groups—to return to the bison-rich plains.
After crossing the Bitterroot Mountains on what is known today as the Lolo Trail, the expedition divides forces at Travelers’ Rest. Lewis takes one group east and north up the Blackfoot River and then over Lewis and Clark Pass. They return to their old camp above the Great Falls of the Missouri to retrieve supplies and specimens cached there.
From Travelers’ Rest, Clark goes up the Bitterroot River and crosses the Continental Divide at present Gibbons Pass. They cross the Big Hole Valley and return to Fortunate Camp where they had cached tobacco, food, and most of the canoes.
At the Headwaters of the Missouri, Sgt. Ordway’s detachment paddles the canoes down the Missouri destined for the portage of the Great Falls. Clark’s group–along with all the horses—travel up the Gallatin River valley on their way to the Yellowstone River.

François Labiche
Private
Labiche performed all the regular duties of an army private, but also performed well as a French and English interpreter. He would continue serving as an escort with Lewis for Chief Sheheke’s delegation to Washington City.
John Collins
Private
He had gotten off to a bad start, but apparently, the captains, or at least Clark, saw something in him that was worth saving. They would name Idaho’s Lolo Creek, Collins Creek.
John Ordway
Sergeant
Ordway’s journal is the only one carries an entry for every one of the trek’s 863 days. Just after the expedition ended, Ordway had purchased the land warrants issued to Jean-Baptiste Lepage and William Werner.

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.
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.
Scientific Explorations
Their work in the emerging fields of botany, ethnography, geography, geology, and zoology are now considered classics of early American scientific literature.
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 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.
Tools and Techniques
A Military Corps
Throughout the expedition the soldiers were expected to conform to the rules and routines of the frontier soldier of 1803.
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.
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.
Expedition Members
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.
Related Explorers
Lewis and Clark were among several significant explorers of North America both before and after the expedition.
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.
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.
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.
