Rapid City Regional Airport (RAP) in South Dakota is welcoming travelers with a temporary art exhibition, “The Science at SURF: Images from the Underground, Lead, SD.”

Located in the former site of the Homestake Gold Mine, SURF is now an underground research facility whose tagline tells us, “Scientists probe the depths of space to learn more about our place in the universe.”

The exhibit includes photographs snapped within the Sanford Underground Research Facility (SURF) by SURF photographers Matthew Kapust and Stephen Kenny. Here’s a sampling.
