An original antique map of Iowa and eastern Nebraska at an important time in the development of both. Nebraska, which did not become a state for another five years, had lost the top two thirds of its original territory (that part became the Dakota Territory) in 1861. Most of the western emigration at the time was passing further to the south, but there was some development along the Missouri River between Iowa and Nebraska, and along the Platte River. Iowa is shown well settled here, but Nebraska has development only to the east of the 98th meridian, with the entire western part of the territory not even shown on this map. An indication is made of a proposed route for the Pacific Railroad, running through Nebraska. A detailed and interesting picture of this region towards at the end of the Civil War. This version is updated from the first edition of 1864 in adding the Iowa country of Lyon in the top left corner.
