The Colorado Trail is a traditional American cowboy song, collected and published in 1927 by Carl Sandburg in his American Songbag. Sandburg says that he learned the song from Dr. T. L. Chapman, of Duluth, Minnesota, who heard it from a badly injured cowboy being treated in his hospital. The cowboy sang it, and many others, to an audience of patients in his ward. Members of the Western Writers of America chose it as one of the Top 100 Western songs of all time.
