This very early map of Oregon Territory was copyrighted by the firm of Illman & Pilbrow in 1833 and published in Burr's atlas in 1835. A historical and interesting map, it draws on the explorations of Jedediah Smith, Lewis & Clark, the Hudson Bay Company and John Jacob Astor's Company for its remarkable degree of information and accuracy. The Oregon Territory extends all the way east to the Stony Mountains. The northern boundary with the British Possessions is set at 54°40' per the "Boundary of Russian Possessions settled by Convention in 1824." The southern boundary is at 42° per the "treaty with Spain 1819." East of the Stony Mountains, the northern boundary is today's Canadian border and noted as per the "treaty with Gt. Britain 1818." In the south, a remnant of the River of the West theory appears, as the Los Mongos River, that flows to the Pacific from the large L. Timpangos. Information and place names include Friendly Indians, Ft. Clapsop or Ft. George, Edmonton Factory, and more.

A good impression with contemporary color. There are a few faint spots in the bottom blank margin, otherwise fine.
