If you’re looking for an adventurous hike this could be the one for you. Lewis Mine in Telluride, Colorado is above Bridal Veil Falls in the Bridal Veil basin. The Lewis Mill was built in 1907 and is said to be one of the most intact examples of historic mining sites in Colorado. Since it is so remote and only accessible by foot (4 miles from the trailhead), most everything has been left alone up there. It is on the National Register of Historic Places. In 2001, the mill was restored by a State Historical Fund grant and the materials used were flown to the site by helicopter. The elevation at the mine is 12,448 feet above sea level.
