"Geological Map of the United States", Hitchcock, Charles Henry

Compiled by Hitchcock and W.P. Blake, accompanying the report of R.W. Raymond, U.S. Commissioner of Mining Statistics. Chromolithograph printed in nine colors with a table providing an explanatory key to the colors. The carefully drawn map shows considerable geographical detail as well as geological information. A legend shows identifying marks for railroads, military and wagon roads, canals, army arsenals and forts, etc.

References: Phillips (A) 1330.

Condition: A

Backed with Japanese tissue to repair splits, a little toning along some folds. Still a very good example of this large and colorful map.
