"Preliminary Geological Map of Ohio Prepared From the notes of the Geological Corps by J.S. Newberry, Chief Geologist", Newberry, J.S.

This early geological map of the state identifies 13 formations with hand coloring keyed to a legend at right. Above the map is a "Section Through Northern Ohio" which uses the same hand coloring to identify the formations in strata. Below the map is the full-width "Section from Cincinnati to Marietta" which also shows the colored strata. A handsome map from the coloring, fancy titling and the delicate banknote-style border. This is only the third map attributed to Newberry.
