An engineering marvel originally built in 1884, the Georgetown Loop railroad fulfilled the hopes of Georgetown citizens to become a prosperous settlement connected to Denver and points east. In connecting Silver Plume and Georgetown, towns over 2 miles apart, the tracks scaled an elevation of 640 feet over mountainous terrain, requiring trestles, cuts, fills, loops, and curves totaling 4.5 miles. Today the Loop is once again a popular tourist attraction and an uncommon way to see the Clear Creek Valley. Along the route visitors may stop for guided tours of a historic silver mine. The park is located on 978 acres and includes an 1884 depot, the Morrison Interpretive Center, two 1860s mines, an 1871 mill building, four reconstructed mine buildings, a locomotive maintenance building, the 1874 Pohle House, and a new rolling stock shelter.
