From Rapid City Journal, Nov. 29, 2017: For more than five years, Ross Shaft crews have been stripping out old steel and lacing, cleaning out decades of debris, adding new ground support and installing new steel to prepare the shaft for its future role in world-leading science. On Oct. 12, all that hard work paid off when the team, which worked its way down from the surface, reached a major milestone: the 4850 Level. Deputy Director Chris Mossey weighs in.

For the first time, scientists have measured the rate at which high-energy neutrinos are absorbed by our planet, a development that could lead to discoveries about physics and Earth.
