Long blue cave, April 2011

Long blue cave, April 2011

Sanford Underground Research Facility staff were lining up for a group photo during this long exposure. The camera was mounted on a tripod to accentuate the movement of the cap lamps. This image was used in the April 2011 issue of Discover magazine. Photo credit: Steve Babbitt.
