"A Geological Map of the United States", Hinton, John Howard

This map of the United States identifies 9 different geologic types including anthracite, bituminous coal, sandstone, and trap rocks extending from the eastern seaboard to the Rocky Mountains (although the hand coloring on this particular example does not follow the template). In addition to the geologic features, the map identifies Indian tribes, rivers, and the Chippewayan Desert. The Pacific Northwest is labeled Western Territory and extends well into British Colombia, reflecting United States claims in the region. Fancy lettering and flourishes in title with the extremely faded imprint of I.T. Hinton & Simpkin & Marshall, dated March 15, 1832. Engraved and printed by Fenner Sears & Co.
