The river is deep, but with little current, and from seventy to one hundred yards wide; the low grounds are very narrow, with but little timber, and that chiefly the aspen tree.

The cliffs are steep, and hang over the river so much that often we could not cross them, but were obliged to pass and repass from one side of the river to the other, in order to make our way.

In some places the banks are formed of dark or black granite rising perpendicularly to a great height, through which the river seems, in the progress of time, to have worn its channel.

On these mountains we see more pine than usual, but it is still in small quantities.

Along the bottoms, which have a covering of high grass, we observed the sunflower blooming in great abundance.
