Deep Underground Science and Engineering Laboratory, Underground research laboratory in Lead, South Dakota, United States.
The Deep Underground Science and Engineering Laboratory is a research facility housed in a former gold mine south of Lead, situated roughly 2,250 meters (7,400 feet) below ground level. The site contains numerous laboratories and experimental spaces where scientists work on investigations across multiple fields.
The Homestake Mine was founded in 1876 during the Black Hills Gold Rush and operated as a mining operation for over a century. In 2007, it was converted into a scientific research center now used for experiments in physics.
The location draws scientists and students who work together in deep underground spaces, making it a meeting point for researchers focused on unlocking mysteries of the universe.
Access to the facility is limited to authorized visitors since it operates as an active research center. The underground location means conditions remain stable, providing a controlled environment for sensitive scientific equipment.
A neutrino experiment at the site sends particle beams through the entire Earth, harnessing this potential to investigate fundamental questions in physics. These experiments benefit directly from the facility's extreme depth, which shields it from cosmic radiation interference.
