The Story

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.

Why it matters

It captures the role of the Monongahela River towns as launching points for the great westward migration that peopled the Ohio Valley and beyond.

West Newton

West Newton, PA · est. 1946

On the banks of the Youghiogheny here, a band of New England pioneers led by General Rufus Putnam built the boats that would carry them west to found Marietta, Ohio. Embarking on April 2, 1788, these veterans of the Revolution went on to organize the first civil government in the Northwest Territory, planting the institutions of the new republic beyond the mountains. West Newton served as their launching point into a vast, freshly opened frontier.

Steamboat Enterprise/Boatbuilding Center

Brownsville, PA · est. 1994

Along the Monongahela at Brownsville, the steamboat Enterprise was built in 1814 with an engine designed by Daniel French and, under Captain Henry M. Shreve, steamed to New Orleans and back—the first vessel to ascend both the Mississippi and Ohio Rivers under steam. The feat proved that western rivers could be navigated upstream, transforming inland commerce. For over a century, the boatyards of Bridgeport and Brownsville turned out flatboats, keelboats, and more than 700 steamboats that carried trade and settlers into the American interior.
