This map accompanied 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 down to the Columbia River. Among the many interesting details are the locations of the various trading posts or forts connected with the northwestern fur trade, both American and British. The map covers present day Oregon, Washington, Idaho, Montana, and Wyoming. The region west of the Rocky Mountains is named Mandan District. It also shows much of southwestern Canada.
