Deep Underground Science and Engineering Laboratory, but that project was instead awarded to the Homestake Mine (South Dakota). Parts of the laboratory had been open for daily tours, and there was an annual open house with more access to the facilities and representatives of the experiments to help with the tours and answer questions. The laboratory, along with public tours, were closed circa 2016.
The Deep Underground Science and Engineering Laboratory was initially assigned to the Homestake Mine in South Dakota instead. Visitors could explore parts of the lab on a daily basis, and an annual open house event provided more access to the facilities and allowed participants to interact with experiment representatives during tours. The laboratory, along with its public tour program, ceased operations around 2016.
