"The United States", Cummings & Hilliard

This early geological map of the United States is the frontispiece for An Elementary Treatise on Mineralogy and Geology, Designed for the Use of Pupils. The map's geology is by Parker Cleaveland and was drawn by H. Morse. It extends into Texas to include San Antonio. Contains great watershed detail and uses hand coloring to suggest five or six geologic types. Marcou states that this map is a reissue of the 1817 Maclure's Geological Map "with very few additions or variations." Issued in one of the most famous and widely used mineralogical reference works in early 19th century America.
