The point where the Allegheny and Monongahela Rivers meet to form the Ohio River has been a meeting point and site of commerce and conflict for thousands of years. Delaware, Shawnee, Haudenosaunee, and many other people frequently took boats from here to the Mississippi River, or even all the way to the Gulf of Mexico.  

By 1800, Pittsburgh was populated by European-American settlers and was known for its boat-building industry.

Meriwether Lewis was familiar with this place: he had been stationed here two years earlier at Fort Fayette, an American fort that served as a supply depot for other forts on the Ohio. Lewis ordered goods for the expedition to be shipped here.

Lewis needed a boat that could take him upstream—he knew they’d be navigating the Missouri River against the current.  

Canoes, dugout boats, and bateaux (flat-bottomed, lightweight riverboats) had long been used to transport materials up or down the river, but they had limited cargo capacity. Keelboats—in heavy use by the 1790s—could transport forty to fifty tons of material upriver quickly due to their long, narrow shape, heavy wooden keel, and pointed prow. Men used iron-tipped poles to push against the river bottom and cajole the boat upstream. 

When Lewis arrived at Fort Fayette on the afternoon of July 15, 1803, he saw only the skeleton of the fifty-five-foot keelboat that was supposed to be ready for him. And the boat builder was drunk.

Lewis waited six weeks for the boat to be ready. While he waited, Lewis prepared for the journey. He recruited new crew members.

He waited to hear back from William Clark, whom he asked to join him as co-commander of the expedition.  

He also worried. The water level dropped as the summer wore on. Would there be enough clearance or current for the boat to move easily down river?

He paid a river pilot, T. Moore, to get the boat and crew to the Falls of the Ohio River.

As soon as the boat was ready—August 30, 1803—they hopped on board and set off.
