About one half mile above this point lay the Great Crossings of the Youghiogheny River, where George Washington crossed on November 18th, 1753, when sent as envoy by Gov. Dinwiddie of Virginia to the French commandant at Fort Le Boeuf. During Washington's military expedition to the Ohio, he encamped there with his forces from May 18th to 24th, 1754, and from that point explored the Youghiogheny. Major General Braddock also crossed there with his army on June 24th, 1755, on his march against Fort Duquesne.
