This early geological map of the United States is bound into the back of volume two of An Elementary Treatise... by Parker Cleaveland. The map's geology is by Cleaveland and was drawn by H. Morse. It extends into Texas to include San Antonio, and uses hand coloring to depict five or six geologic classifications. Marcou states that this map is a reissue of the 1817 Maclure's Geological Map "with very few additions or variations". In addition to the map, there are five geological plates also bound into the rear of volume two. Second edition, 796 total pages in two volumes with index and explanation of plates. Octavo, rebound in tan buckram with red title label on spine. One of the most famous and widely used mineralogical reference works of the early 19th century in America.

The folding map has light scattered foxing, a short binding tear at right, and a 2" fold separation at lower right that has been repaired on verso with old paper. The text and additional plates have light toning and occasional scattered foxing. A previous owner's signature is on the title page of volume one. Modern binding is excellent with slightly bumped edges.
