Excavation in South Dakota is halfway complete

The excavation of the underground area for the South Dakota portion of the Deep Underground Neutrino Experiment is halfway complete. Almost 400,000 tons of rock have been excavated so far.

The operations team that works underground each day consists of roughly 115 people. And many other people support their work from above ground. See this article for more details.

Thank you all for your work!

When complete later this year, this cavern will be around 500 feet long, 65 feet wide and 90 feet high. It will be one of three caverns that will provide space to house particle detector modules and other equipment for the Deep Underground Neutrino Experiment. Photo: David Smith, Fermilab
