The import of the map is the Union Pacific's promotion of rail travel to Denver as a means of seeing the Rocky Mountains by car, as the main lines in red promote the available scenic and historic driving routes through the region. The map is reflective of the beginning of America's romance with the automobile and the era of "Over Loving" the US national parks, which resulted in a boom in commercial exploitation and over development of the park system.
