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.

What to Expect:

  • The Orphan Girl 100-foot level tour takes you to the original workings of the mine. Mud is likely.
  • The mine is a constant 45 to 50 degrees year round.
  • This tour is an all walking tour. Close toed shoes are preferred.
  • Visitors are fitted with miners’ hard hats and cap lamps. The cap lamps are the only lights underground except for two, which are used to highlight the shaft to the water. All equipment is sanitized between tours.
  • The mine workings are not ADA compliant and walking 180 feet of entrance ramp is ordinarily required; however, visitors with limited mobility may be accommodated for much of the tour. There is a 12% slope although there are no stairs.
  • ANY participant has the option to turn around at any time.
  • GENERAL ADMISSION IS INCLUDED WITH THE PURCHASE OF AN UNDERGROUND TOUR TICKER. Guests may tour the 22+ acres of Museum prior to or after their guided tour as time permits.

  • Closed-toed walking shoes and light jackets are recommended.
  • Members must provide proof of membership at check-in.
