Here is an interesting picture of Colorado State grasslands.  This photo was taken just outside Trinidad Colorado.  It is a picture of what remains of an old western frontier building resting comfortably on the prairie with the Rocky Mountains as a backdrop.  Trinidad was known as a coal mining community.  You can see the scars on the sides of the mountains and in the valleys from the early days of mining.  The city sits on the bottom of the Raton pass into New Mexico.
