This uncommon map of the Arctic extends from the Great Bear Lake in the north and follows the MacKenzie River to its source in the Great Slave Lake, and shows a dashed line indicating the route of Captain John Franklin's expedition in 1827. The map provides information reflecting the progress of explorations in that region, with many notations detailing geographical conditions. The Mackenzie Mountains are here called the Rocky Mountains, and the locations of various Indian tribes are noted.
