This is Johnson and Ward’s rare 1863 map of the territories of Idaho, Dakota, Nebraska Colorado and Kansas.  Depicts this area during an interesting transitional phase shortly following the formation of Idaho in 1863 but predating the formation of Montana in 1864.   Thus we see a massive Idaho consisting of all of modern day Wyoming, Idaho and Montana.  Shows the three proposed routes of the Pacific Railroad including the northern route, as suggested by Governor Stevens, the central route proposed by Lieutenant Beckwith, and the southern route as suggested by Captain Gunnison.   Features the fretwork border common to Johnson’s atlas work from 1863 to 1869. Steel plate engraving prepared by A. J. Johnson for publication as plate no. 55 in the 1863 edition of his  New Illustrated Atlas…   This is the last edition of the Johnson’s  Atlas  to bear the Johnson and Ward imprint.
