Its junction with the Clear Water River is called the Forks.
Its banks were in accessible cliffs, apparently of clay and stones, about two hundred feet high, and its windings in the south were encircled by high mountains.

Its breadth exceeded half a mile and was swelled to a mile in many places by long muddy islands in the middle covered with trees.

No more portages interrupted our course, but a swift current hurried us towards the quarter in which our anticipated discoveries were to commence.

The passing cliffs returned a loud confusion of echoes to the sprightly canoe song, and the dashing paddles; and the eagles, watching with half-closed eyes on the pine-tops, started from their airy rest, and prepared their drowsy pinions for the flight.
About twenty miles from the Forks are some salt pits and plains, said to be very extensive.

The height of the banks was reduced to twenty or thirty feet, and the hills ranged themselves at an increased distance from the banks in the same variety as those of the Clear Water River.
