This map was issued in an important report intended to awaken public interest in the American occupation of Oregon Territory in the controversy with Great Britain, who also claimed the territory south to the Columbia River. Among the many interesting details on the map are the locations of the various trading posts or forts connected with the American and British northwestern fur trade. It covers present day Oregon, Washington, Idaho, Montana and Wyoming. The region east of the Rocky Mountains is named Mandan District. It also shows much of southwestern Canada. The map was copied from John Arrowsmith's 1832 map of British North America. At lower left is the wording of an ultimatum given to the British by Henry Clay, Secretary of State, stating that the 49th parallel will be the boundary. Engraved by M.H. Stansbury.
