Lewis and his men camped about two miles above the state line dividing Virginia, now West Virginia, and Pennsylvania on the east side of the river and Pennsylvania from Ohio on the west. The line was visible where timber had been felled about 60 feet in width, and although young timber had sprung up, it had not yet reached the height of the surrounding trees, so the line could still be traced for a considerable distance. It crossed the Ohio River at the mouth of Mill Creek. Lewis also noted the low, clear water, where many kinds of fish could be seen, including sturgeon, bass, catfish, and pike. As the Corps of Discovery traveled down the Ohio River, it gathered men and supplies; Lewis began keeping his journal in Pittsburgh, and Clark joined him at the Falls of the Ohio as the first of the great expeditions began.
