Woollery's Trap
At McKees Rocks below Pittsburgh, heavy fog delays departure. Lewis suspects the area's frequent morning fogs are caused by the Ohio River water being warmer than the air above it. At Horsetail Ripple, they must unload the barge and lift the empty boat over. The process is repeated at Woollery's Trap with the addition of a team of oxen. They [...]
Leaving Calumet Bluff
Leaving Calumet Bluff, the expedition say goodbye to Pierre Dorion and the Yankton Sioux hoping the old trader can treat for peace and send delegates to Washington City. They camp at Bon Homme island, now inundated behind Point Gavins Dam. Several catfish are caught, and Lewis collects a specimen of wild four-o’clock.
Up "Fish Creek"
In the morning, the expedition climbs out of Tower Creek where a horse slips and rolls backwards. York's feet become so sore that he must ride a horse. They descend to the North Fork Salmon River where some men gig several salmon. Camp is near present Gibbonsville, Idaho.
Return to Calumet Bluff
On their return to Calumet Bluff near present Yankton, South Dakota, Clark expresses relief when a group of shooting Indians turn out to be Yankton Sioux. From them, they hear news of Pierre Dorion, Sr. and the fur trade. In the evening, they camp opposite their council site of 1 September 1804.
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.

21 August–8 September 1804
Moving along the present border between Nebraska and South Dakota, the expedition turns its ‘enlightened‘ attention to several features in the upper Missouri River mythology.
Instead of a volcano, they find blue earth, cliffs of white marl, and burning bluffs. Lewis becomes ill while testing one of the minerals he found. Instead of La Véndrye’s Golden Sands, they find hills of wind-blown loess. Instead of a Spirit Moundmountain of little people and devilish spirits, they find birds feeding on pissants atop present Spirit Mound.
Pvt. George Shannon fails to return from a hunting trip, and Patrick Gass is promoted to sergeant. At Calumet Bluff, their attention turns to receiving the Yankton Sioux. For two days, a council with speeches, gifts, songs, and dances is held.
At Old Baldy—present The Tower in South Dakota—everybody but the camp guard visits a prairie dog town, and they manage to capture one as a live specimen. He would travel to the Knife River Villages, Washington City, and reside in Peale’s Museum in Philadelphia.
Their encounters here had been encouraging, but Shannon is still missing, and the Lakota Sioux homelands are just ahead.

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.

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.

Private
At Long Camp, Potts nearly drowned when the dugout canoe he was in was swamped in the Clearwater River. But Potts’s worst accident happened when the Corps retraced the Northern Nez Perce Trail through the Bitterroots.

Windsor helped recover three orphaned grizzly bear cubs of a sow they killed on a hunt in early April of 1806. According to Lewis, they traded the cubs to some coastal Indians, who, “fancyed these petts and gave us wappetoe in exchange for them.”
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.

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 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.
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.

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.
Other topics include music, holidays, High Potential Historic Sites, and an index of articles from We Proceeded On.
From clichés and colorful sayings of the time to Native American languages, these pages feature the art of language.
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 left behind among many Indians a legacy of nonviolent contact. Those who came later enjoyed that legacy and too often betrayed it.
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.
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.
Their work in the emerging fields of botany, ethnography, geography, geology, and zoology are now considered classics of early American scientific literature.
Throughout the expedition the soldiers were expected to conform to the rules and routines of the frontier soldier of 1803.
Lewis and Clark were among several significant explorers of North America both before and after the expedition.
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.
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.
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.
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.
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.
