Colton pocket map of Iowa
Iowa experienced explosive growth during the 1860s, largely as a result of the rapid development of the state's railroad system. At the beginning of the decade, Iowa's few railroads were entirely confined to the eastern one-third of the state. By the time Colton published this fine map in 1869, several lines had pushed to its western border, including the Mississippi & Missouri Railroad, which joined the transcontinental railroad at Council Bluffs.
This map is similar to another one published by the Coltons in the same period, though smaller and without the "sectional" divisions.
