Black Hills Pioneer, September 19, 2026
Crews at the Sanford Underground Research Facility have moved about 39% of the I-beam steel needed to construct the cryotat for the Deep Underground Neutrino Experiment. That represents nearly 2 million pounds of steel that completely fills the south cavern that is 500 feet long, 65 feet wide, and about 7 stories tall.
