Note: "This is a very unusual map for Rand McNally to issue - geological maps were not common in their catalog and this may be the only one they published. It was probably the interest in mining that motivated publication and the inclusion of ""Mineralogical References"" in the map key. The main source for the geological formations was Hayden's General Geological Map of Colorado that appeared in his 1877 Atlas of Colorado. But Rand McNally's map has much more detail on towns and railroads than Hayden and is a much superior map in that respect. Ellis 82 is the 1880 edition, which was also issued without geological coloring as ""Rand McNally & Co.'s New Sectional Map of Colorado."" This map is in printed full color, folded into dark blue cloth covers 16.5x10 titled ""Rand, McNally & Co's geological and mineralogical maps Of Colorado"" in gold."
