Lewis and Clark Expedition

Pittsburgh, Allegheny County, Pennsylvania

Marker Inscription

On Aug. 31, 1803, Capt. Meriwether Lewis launched a 50-foot "keeled boat"ย from Ft. Fayette, 100 yards downriver. This marked the beginning of the 3-year expedition commissioned by President Jefferson, which opened America to westward expansion.

The Story

On August 31, 1803, Meriwether Lewis eased a 50-foot keeled boat into the Ohio River near Fort Fayette, launching the journey that would become the Lewis and Clark Expedition. Commissioned by President Thomas Jefferson to explore the newly acquired lands to the west, the three-year trek pushed all the way to the Pacific and back. Pittsburgh, at the head of the Ohio, was the practical starting line for that continental adventure.

Why it matters

The expedition opened the American imagination โ€” and eventually American settlement โ€” to the vast lands west of the Mississippi, making this quiet riverbank a doorway to the nation's westward story.

Allegheny County

Pittsburgh, PA

When Allegheny County was carved out of Westmoreland and Washington counties in 1788, its seat at Pittsburgh was already a generation old โ€” laid out in 1764 at the strategic forks where the Allegheny and Monongahela join to form the Ohio, a gateway that had drawn soldiers, traders, and settlers pushing west. Incorporated as a city in 1816, Pittsburgh grew into one of the great engines of American industry, its furnaces and mills pouring out the iron and steel that earned the region its "Workshop of the World" reputation. The county's story runs straight from a frontier river junction to the smoke-and-fire heart of the nation's industrial age.

Steamboat "New Orleans"

Pittsburgh, PA ยท est. 2011

On October 15, 1811, the side-wheeler New Orleans slid into the Monongahela near Suke's Run โ€” the first steamboat ever built west of the Alleghenies. Its launch proved that steam power could conquer the powerful currents of the Ohio and Mississippi, and Pittsburgh, already rich in iron and timber, quickly became a bustling yard for building the boats that carried a nation west.

Monongahela

Monongahela, PA ยท est. 1947

Monongahela is remembered as the oldest settlement in its valley, a river town whose life turned on the water from the very start. Devore's Ferry, chartered in 1775, made it a crossing and transportation hub long before the town was laid out in 1796 as Williamsport, and it became a city in 1873. From its banks countless pioneers pushed off to begin the river journey westward.
