The First Commercially Published Geological Map of Iowa

A fine large format map of Iowa, published by Nathan H. Parker in Clinton, Iowa and printed by J. H. Colton in New York and Keen & Lee in Chicago. This is one of the earliest appearances of the Keen & Lee name.

Parker was a partner in the Clinton Iowa firm of Parker, Dole & Co. The firm included both bankers and land agents in Iowa during its initial period of settlement following its admission as a state. The map was issued as an inducement to settlement and investment in the region.

Iowa is hand colored by counties, with a list of approximately 16 railroads at the left, including the names of the railroads with which they connect.

The regions where coal, lead, iron and plaster are mined are identified.

Inset map titled "Map Showing the Connections between Iowa and Eastern Rail Roads."
