On this day with Lewis & Clark
November 6, 1803
The Saline River
On or near this date, the expedition passes the Saline River. In 1807, Fortescue Cuming would describe the river’s mouth and a salt works about 20 miles up the river.
November 6, 1804
Northern lights
During the night, the guard wakes the captains so they can view the Aurora Borealis. Joseph Gravelines and four St. Charles boatmen leave for the Arikara villages to promote Mandan-Arikara peace.
November 6, 1805
Among the Cowlitz
The men paddle down the Columbia in the rain interacting with several villages near the mouth of the Cowlitz. In the evening, they build large fires to dry out and kill the fleas infesting their blankets.

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.

Winter at Fort Mandan
26 October 1804–6 April 1805
On 2 November 1804 below the Knife River Villages, work begins on the expedition’s winter fortification. The men’s quarters, storage rooms, and the 16-foot pickets, are designed for defense against hostile Indians, especially the Sioux, who would be quite troublesome, although they never attacked the fort directly. “This place we have named Fort Mandan,” Lewis recorded, “in honour of our Neighbours”—their kind and congenial Mandan Indians. Here they celebrate their second Christmas and New Year’s Day.
On 28 February 1805, sixteen enlisted men are assigned to hew six canoes from cottonwood logs, and they finish them in 22 days. Meanwhile, the rest of the men make rope, leather clothing and moccasins, cured meat, and battle axes to trade for corn. Lewis prepares botanical, zoological, and mineralogical specimens for shipping back to President Jefferson. Clark works on his Fort Mandan maps.
By the time they are ready to leave Fort Mandan, they add some key members to the permanent party: Toussaint Charbonneau, his wife and infant son—Sacagawea and Jean Baptiste, and French trader Jean-Baptiste Lepage. Each would play critical roles in the expedition’s journey to the Pacific Ocean.

Down the Columbia
18 October–6 December 1805
In five battered dugout canoes, the expedition paddles down the Columbia River—a river that they know will take them to the Pacific Ocean. They safely pass a series of rapids and falls between Celilo Falls and the Cascades of the Columbia. In the Columbia River Gorge, they see stunning geologic features.
The river calms, and they enter one of the most populated areas of their entire journey with numerous villages of Upper and Lower Chinook. Nearing the ocean, they find the Columbia River estuary is miles long and miles wide. They must hunker down in small nitches on the northern shore several days before they can reach the end of their water journey at Baker Bay.
At Station Camp, the captains survey the party as to where they would like to spend the winter. Everyone’s opinion—including York and Sacagawea—are written down. They decide to cross the river where according to the Clatsops, there are many elk. They set up a camp on a narrow spit of land on the opposite side—present Tongue Point at Astoria, Oregon. Lewis takes a small party to find a suitable location to build a fort, but when he fails to return after five days, Clark begins to worry.

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.

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 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.
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.
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.
Synopsis of the Expedition
by Harry W. Fritz
The entire story is told in these five webpages.
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
Explore the methods they used to get stuff done—from building canoes to making rope.
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.
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.
Related Explorers
Lewis and Clark were among several significant explorers of North America both before and after the expedition.
Scientific Explorations
Their work in the emerging fields of botany, ethnography, geography, geology, and zoology are now considered classics of early American scientific literature.
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.
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.
A Military Corps
Throughout the expedition the soldiers were expected to conform to the rules and routines of the frontier soldier of 1803.
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.
Other Topics
Other topics include music, holidays, High Potential Historic Sites, and an index of articles from We Proceeded On.
