Employees from Thyssen Mining complete construction of a temporary work platform over the main ore pass on the 4850 level. All blasted rock from the project will be dumped down this pass before being hoisted to surface.

From the Black Hills Pioneer, Aug. 21, 2021: The former Homestake Gold Mine in Lead, SD was dedicated as the M. Michael Rounds Operations Center at the Sanford Underground Research Facility. The dedication event included remarks from many dignitaries including Sanford Lab Executive Director Mike Headley, who talked about the long journey it has been to support the new facility and that Sanford Lab has made great strides toward building the LBNF that will house the Deep Underground Neutrino Experiment at 4,850 level, led by Fermilab.

An illustration. I person stands inside a giant, hollow gold cube and sends a signal using a device to another device on the left side of the screen that is close up and held in a hand. The close-up device says "counting" and has some numbers. In the bottom right-hand corner, it says LBNF/DUNE.

When studying mysterious subatomic particles, researchers at SURF in South Dakota use a different kind of particle detector, particle counters, to prevent run-of-the-mill dust particles from creating background noise and obscuring results.

Sanford Underground Research Facility is making an effort to build bridges with Native American communities and operate with respect for the sacred land it is built on.
