Sulfurous springs
In Pittsburgh, Lewis oversees construction of the expedition's military-style barge before departing down the Ohio River. The high hills surrounding the city are so impregnated with coal that the springs issuing from them taste of sulfur.
Dragging for fish
At Fish Camp near present Homer, Nebraska, Clark has a fish net made, and when they drag it through a nearby beaver pond, they catch over 300 fish. When smoke appears in the distance, fur trader Pierre Dorion leaves to find Indians.
Reluctant Shoshone helpers
The enlisted men endure another day moving the heavy dugouts up the shallow Beaverhead River. Clark, Charbonneau, and Sacagawea walk the shore where they encounter several rattlesnakes. They encamp at present Clark's Canyon. In the Lemhi Valley, Lewis discovers that the Lemhi Shoshones have become suspicious of his motives and are reluctant to travel with him. Eventually, most of the [...]
Broken promises of peace
Having returned to the Knife River Villages in present North Dakota, the captains hear of several broken promises of peace among the several tribes with whom they thought peace treaties were in place. Pvt. Colter asks to leave the expedition so that he can go back west with two fur trappers.
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.

Following the Missouri River north along the present Nebraska-Iowa border, the expedition passes the homelands of the Otoes and Omahas. The captains pay their respects to the late Omaha Chief Blackbird and conduct their first two councils, one with the Otoes and another with the Omaha.
Strong currents, heat, sandbars, sawyers, and masses of driftwood make hard days for the enlisted men and engagés, and Pvt. Moses Reed and an engagé desert.
Shortly after the council with the Omahas, Sgt. Charles Floyd becomes ill, and passes away. He is buried “with all the honors of War” on a bluff overlooking the river in present Sioux City, Iowa.

Above the Great Falls of the Missouri, the expedition continues up the Missouri River in eight dugout canoes. There, the river flows along and through the eastern arms of the Rocky Mountains. Clark lists each river constriction as a gate, gap, or narrow.

Below Three Forks, Montana, the Missouri River ends—fed by three forks named by the captains: the Gallatin, Madison, and Jefferson. They continue up the Jefferson until it too forks into three rivers.
The Beaverhead River is only a sixth the size of the Missouri, and the enlisted men must walk the heavy dugouts up the shallow rapids. They are encouraged when Sacagawea sees familiar landmarks such as Beaverhead Rock.
To get to the waters of the Columbia, they would need horses. The captains take turns scouting ahead by land to find the Shoshones who they hope will have horses. While crossing the Continental Divide at Lemhi Pass, Lewis finally meets them.
Clark would continue with most of the party moving the boats up the shallow Beaverhead. By the time they reach the end of the navigable river, Lewis and a group of Shoshones are waiting for them. One journalist would later name the place Fortunate Camp.

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.

Miller’s reputation rests on his single Green River Rendezvous trip from which he transformed his original sketches and notes into a lifetime of images. His work preserves details of clothing, equipment, camps, transport, and performance. At the same time, his images were made for patrons who valued romance and spectacle. For that reason, Miller should be read carefully.
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.
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.
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.
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.
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.
From clichés and colorful sayings of the time to Native American languages, these pages feature the art of language.
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.
Throughout the expedition the soldiers were expected to conform to the rules and routines of the frontier soldier of 1803.
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.
Lewis and Clark were among several significant explorers of North America both before and after the expedition.
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.
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.

Their work in the emerging fields of botany, ethnography, geography, geology, and zoology are now considered classics of early American scientific literature.
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.

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.
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.
