From Sanford Underground Research Facility, Aug. 4, 2020: The most publicly visible milestone of the Long-Baseline Neutrino Facility’s pre-excavation work, a conveyor system, now extends over U.S. Highway 85 in Lead, South Dakota. Installation of the conveyor is one of a series of infrastructure strengthening projects undertaken to prepare the Sanford Underground Research Facility for its role as LBNF’s far site. Such projects lay the groundwork for the Deep Underground Neutrino Experiment, the most ambitious particle physics experiment on U.S. soil, hosted by Fermilab.

From Black Hills Pioneer, July 22, 2020: Since late 2019, work has been underway on the Long-Baseline Neutrino Facility conveyor system at the Sanford Underground Research Facility in South Dakota. The system will carry more than 800,000 tons of rock excavated from the site of the international, Fermilab-hosted Deep Underground Neutrino Experiment 4,850-feet below the surface. A major milestone for the project was met on July 20 as the 120-foot section of the truss, which will house the conveyor, was erected above the highway.
From Gizmodo, May 18, 2020: Neutrino physics is a trek into the unknown, one that the United States physics community has chosen to pursue full-on. A flagship experiment called LBNF/DUNE will lead the search, in pursuit of answers that may take decades or more to find. Fermilab Deputy Director for Research Joe Lykken, DUNE spokesperson Ed Blucher, and DUNE scientists Chang Kee Jung and Elizabeth Worcester talk about how neutrinos will enhance our understanding of the universe.
It’s blues and whites at Sanford Lab’s Ross Headframe after a big snowstorm on Feb. 25. The area saw 30 inches of snow that day.
From News at South Dakota State, Feb. 25, 2020: Two South Dakota State University professors are part of an international team of scientists and engineers working to uncover details about how the universe was formed. Stephen Gent and Greg Michna are using SDSU’s high-performance computing cluster to predict how argon circulates within the particle detectors to be constructed one mile beneath the earth’s surface. The detectors are for Fermilab’s Long-Baseline Neutrino Facility/Deep Underground Neutrino Experiment, which will be installed in the Sanford Underground Research Facility in Lead, South Dakota.
From Tunnels and Tunneling, Feb. 19, 2020: Three of the underground construction components are near completion at the Sanford Underground Research Facility for the far site of Fermilab’s Long-Baseline Neutrino Facility. Work is finishing up on two ore passes that connect the 4850 Level, almost one mile underground, to skips in the Ross Shaft; the Ross Headframe, which must support the skips that bring the rock to the surface; and the tramway tunnel, which will house the conveyor system that will transport excavated rock to its final location.
From Black Hills Pioneer, Feb. 19, 2020: Data from the Deep Underground Neutrino Experiment could help physicists explain the origin of matter, witness a never-before-seen particle decay and better understand how black holes form in space. To prepare for this groundbreaking science, a major construction project is under way to ready the Sanford Underground Research Facility for its role as the far site of Fermilab’s Long-Baseline Neutrino Facility.
The pre-excavation phase involves the reopening, rehabilitation and reinforcement of infrastructure created for gold mining operations decades ago.
From Black Hills Pioneer, Dec. 13, 2019: Scientists at Fermilab and the Sanford Underground Research Facility in South Dakota are eager to begin collecting data from the Long-Baseline Neutrino Facility and the international Deep Underground Neutrino Experiment, which is hosted by Fermilab. But before the world’s largest neutrino experiment can begin producing results, more than 800,000 tons of rock will need to be removed from the 4,850-foot level of a former mine to make room for the detectors.
From Rapid City Journal, Nov. 28, 2019: The Ross and Yates Shafts were built in the 1930s and served as powerhouses for Homestake Mining Company for years. When asked what is most remarkable about these shafts, the experts unanimously agree — the engineering and craftsmanship that allow these shafts to be used to this day by Sanford Underground Research Facility.
