Core Repository Will Open October 29

With the moving trucks parked, the core boxes rearranged, and the dust barely settled, the IGWS Core Repository will reopen on Monday, October 29, 2018. The cores are now housed in the former Otis Elevator warehouse at 1425 S. Curry Pike, Bloomington, Ind.

"With the help of Iron Mountain [a specialized collections relocation company], we moved 400 tons of material---that's 51 miles of rock core---in less than a month," said Todd Thompson, IGWS Director and State Geologist. “I wish we were in better shape. We will get there over the coming months as we rebox and reshelve the core. Regardless, we know where every core is and can get it for anyone needing subsurface data."

Previously housed in a 4,000-square-foot building in compact storage, the core samples are now available for research and study in a 50,000-square-foot warehouse. The core boxes are contained on pallets that are spread out in the larger building.
