1874 Asher & Adams Colorado

This is an authentic antique map of Colorado detailing surveyed land and the network of railroads during the mid 1870s. The map was published as part of an atlas by Asher & Adams out of New York, NY. Cartographic detail includes established cities, mining towns, military forts, and the delineation of mountain river systems with no attention paid to the topography of the Rocky Mountains. Breckenridge is shown within a Summit County that encompasses the entire northwest portion of the state. Many of these large counties would be broken up and reconfigured as more miners and settlers moved in establishing many new towns along the way. Asher & Adams was one of the first United States atlases to exclusively feature railroad lines, showing minimal topography. This later state shows more topographical features than did earlier editions. Only towns that were near or on the railroad lines were featured in earlier editions.
