St. Elmo is one of the best preserved ghost towns in Colorado. Founded in 1880, St. Elmo sprang to life and provided a place to stay for miners who worked at various mines around the mountains. It reached a peak population of just over 2000 and even had it's own weekly newspaper, the Mountaineer. St. Elmo thrived up unitl 1910, when many mines started to fail and the Alpine Tunnel closed. By 1926, all but one family had moved out of the town.
Currently, most of the buildings are privately owned and the entire town is in an excellent state of preservation. Though not a true "ghost town," it definitely gives one a sense of what it was like to live in a small mountain town way back in the day.
