Located 2341 feet beneath the surface, in an old iron mine,
the lab is deep enough that particle physics experiments see less than
100,000 times the cosmic radiation than on the surface, allowing
sensitive searches for exotic particles like neutrinos and dark matter.
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
