According to this website, “St. Elmo Colorado was officially founded in 1880. Gold and Silver Mining brought many people to the area. There were over 150 Patented mine claims in the St. Elmo area. Populations reached a high of nearly 2000 people. The DSP&P laid their tracks up to St. Elmo and continued the line through Romley then to Hancock and through the Historic Alpine Tunnel. St. Elmo was considered a Hub town for supplies arriving by train. The tracks were abandoned in 1922. It is said that St. Elmo’s Population rode the last train out of town and never came back.”
Several buildings remain abandoned in the town (although they are being preserved and stabilized by a historical society), and you can visit them and also feed the abundant chipmunks living in the town.
