Sanford Underground Lab
- Dignitaries and board members applaud South Dakota Gov. Mike Rounds, at the podium, during dedication ceremonies Monday, June 22, 2009, at the future site of the Sanford Underground Science and Engineering Laboratory. The event occurred at the 4,850 foot level of the former Homestake gold mine at Lead, S.D. In the near future, scientific experiments dealing with dark matter and numerous other ideas will be set up in the mine shafts nearly a mile underground, shielded from cosmic rays.
