This colorful geological map focuses on the United States, but also includes a good portion of Canada and the Baja. It identifies twelve different geological types by color. This updated German edition presents much of the same information as Marcou's original 1853 map but extends geological coverage to the Pacific and eliminates the geological profile across the top. The copper trap previously shown in the Wind River Mountains is not depicted here. An uncommon edition of Marcou's scarce map published in Petermann's Geographische Mittheilungen.
