Johnson’s map of the northern plains issued in 1863, the year that the eastern part of Washington Territory and the western part of the vast Dakota Territory shown on the map above were broken off to form the Idaho Territory, which also took the western part of Nebraska. This new territory encompassed what today is Idaho, Montana and Wyoming. This map shows the eastern part of the Idaho Territory, along with the territories and states to the east and south. The following year, the northern part of that section of Idaho shown here was formed into the Montana Territory, so this map captures a political configuration which lasted but a year.
