Jefferson's surprise
In Philadelphia, Lewis has a painted chest made to hold his scientific instruments. In Washington City, Thomas Jefferson receives the news that France wishes to sell their entire Louisiana colony. Unknown to anyone in the United States, the actual purchase treaty has been signed.
Hitting a snag
After passing Arrow Rock in present Missouri, the barge (keelboat) hits a snag and turns sideways to the current exposing it to drifting logs. The enlisted men struggle to get her off before she is injured. Camp is near present Richland Creek.
The southern fork
At Decision Point, the captains use their maps, intelligence gathered from Indigenous informants, and their own observations to decide they will continue up the southern fork (the Missouri). All the enlisted men think the northern fork (the Marias) is the correct way to go. They dig a cache, prepare to abandon the red pirogue, and pass the night in song [...]
Falling river, rising hopes
At Long Camp, everything is ready for tomorrow's move to Weippe Prairie. Neesh-ne-park-ke-ook (Cut Nose) harvests eagle feathers by capturing live birds from their nests, and the falling river gives hope that the mountain snows have melted. Lewis takes celestial observations and collects a specimen of varileaf phacelia—new to science.
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.

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.

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.

23 March–9 June 1806
The desire to return to St. Louis motivates the paddlers as they head up the Columbia River. Across from the Sandy River, they stop to hunt and dry meat. They explore the Willamette and Sandy hoping that one of them is the fabled river that comes from California.
Below Celilo Falls, they begin trading for horses and by the time they reach the Walla Walla River, they have enough horses to take the overland Travois Trail back to the Snake River. They then continue by horse up the Clearwater River.
At Kamiah in present Idaho, they establish a “Long Camp” among the Nez Perce to wait for mountain snows to melt. Sgt. Ordway takes a side trip to the Salmon and Snake rivers where some Nez Perce fishers are catching salmon.
After five weeks sharing with the Nez Perce, they head to the mountain trails that will take them to the land of the buffalo.

Interpreter
Speaking Hidatsa and Shoshone, she was an interpreter beyond value yet never on the payroll. Still, Sacagawea remains the third most famous member of the Lewis and Clark Expedition.
Private
On 23 January 1806, Lewis dispatched Howard and Werner to the Salt Camp on the ocean beach, to bring back a supply of salt. When they had not returned by the 26th, Lewis feared they had gotten lost.
Private
Cruzatte’s skills in piloting boats were called on frequently during the expedition. As the main fiddle player, his music brought life to many a celebration. In addition, he could speak Omaha.

The American portraitist, artist and illustrator John Mix Stanley (1814-1872), served as one of the official artists with the Stevens railroad survey party to the Northwest. His record of highlights along the route often combined documentary verisimilitude with romantic fantasy.
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.
Their work in the emerging fields of botany, ethnography, geography, geology, and zoology are now considered classics of early American scientific literature.
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.
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.
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.

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.
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.
Throughout the expedition the soldiers were expected to conform to the rules and routines of the frontier soldier of 1803.
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.
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 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.
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.
From clichés and colorful sayings of the time to Native American languages, these pages feature the art of language.
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.
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.
Lewis and Clark were among several significant explorers of North America both before and after the expedition.
