To reach the Ohio River basins' navigable waters as soon as possible on the Monongahela River, Washington chose to follow Nemacolin's Trail, a Native American trail which had been somewhat improved by colonists, with Nemacolin's help. He preferred this to following the ridge-hopping, high-altitude path traversed by the western part of the route that was later chosen for Braddock's Road. It jogged to the north near the fort and passed over another notch near Confluence, Pennsylvania into the valley and drainage basin of the Youghiogheny River. The Redstone destination at the terminus of Nemacolin's Trail was a natural choice for an advanced base. The location was one of the few known good crossing points where both sides of the wide deep river had low accessible banks; steep sides were characteristic of the Monongahela River valley.
