This interesting map is a revision of Reichard's map of 1818. It shows the United States with its claim into present-day British Columbia, Mexico in control of the Southwest, and Russia possessing Alaska. In the West are the large territories of Oregon, Missouri, North-West and Arkansas. A large inset details the northern Northwest coast with the discoveries of Vancouver.
