Venture 100 feet underground to see the original shaft station and the Orphan Girl vein, one of the few exposed veins in North America that can be seen by the public. The tour guides lead you through the drift, sharing stories as you venture 100 feet into the 2700-foot-deep Orphan Girl Mine. Many other surprises wait for you at the 100-foot level. Be sure to allow extra time to explore the rest of the Museum, 22+ acres, as it is included in the price of your underground tour ticket. Must be at least 5 years of age to take tour.
