Sanford Lab Homestake Visitor Center Tour — Lead, South Dakota

Discover the Sanford Lab Homestake Visitor Center Tour in South Dakota

Located in Lead, South Dakota, in the northern Black Hills, the Sanford Lab Homestake Visitor Center Tour introduces visitors to one of the most unique scientific facilities in the United States. This guided visitor center tour explains the transformation of the historic Homestake Gold Mine into the Sanford Underground Research Facility, where scientists conduct cutting-edge physics experiments deep underground.

Visitors explore exhibits about mining history, underground science, and particle physics while learning how researchers study neutrinos, dark matter, and other mysteries of the universe beneath the Black Hills.

Why it’s special: Sanford Lab operates one of the world’s deepest underground science laboratories, located inside the former Homestake Gold Mine that once reached depths of more than 8,000 feet.

History & Story of Sanford Lab Homestake

The Homestake Gold Mine began operations in 1876 during the Black Hills Gold Rush and became one of the largest and deepest gold mines in North America. For more than a century, miners extracted millions of ounces of gold from the underground tunnels beneath Lead.

After the mine closed in 2002, the site was transformed into the Sanford Underground Research Facility. Today, scientists use the deep underground environment to conduct experiments shielded from cosmic radiation, enabling groundbreaking research in particle physics and astrophysics.
