Soudan Underground Laboratory Tour

Soudan Underground Lab tour
A group tour at the Soudan Underground Lab in front of the MINOS Far Detector

The Soudan Underground Laboratory is the leading deep underground science and engineering laboratory in the United States today.

Scientists from around the world have been working at Soudan for 25 years trying to answer basic questions about the universe in which we live: Is matter completely stable? What is the nature of the fundamental forces? Can we identify the Dark Matter that seems to permeate our universe? Learn about our first neutrino events using the neutrino beam from Fermilab and see the massive MINOS detector (Main Injector Neutrino Oscillation Search). Learn about CDMS (Cryogenic Dark Matter Search) and its continued search for a WIMP (Weakly Interacting Massive Particles).

Take a tour of the Soudan Underground Laboratory when you are up North. Daily public tours are offered Memorial weekend thru September and the first three weekends in October. Groups of 10 or more and educational tours are available off season by pre-arrangement with a 15 day advance notice. Contact the Soudan Underground Mine State Park for tour times and availability at 1-218-753-2245 or [|].
