Hitchcock's landmark geological map of the United State and southern Canada was published between 1853 and 1856 with no changes. The eastern portion of the map is a compilation of Lyell’s map with the western geology from M. Boue’s Geological Map of the World, modified by the author’s generalizations. This map provides early detail of the geological formations. An explanatory key to the colors indicates fifteen geological formations. Lithographed by W.O. Sharps Lith., Boston. This map was included in Outline of the Geology of the Globe, and of the United States in Particular....

Very nice impression and fine original hand color. There is some toning along the centerfold and where the map attached to the report at lower right. The left margin closely follows the neatline at the binding trim. Folds are reinforced with archival tape on verso.
