The Research and Teaching Core Repository was completed in 1976 and houses drilled cores taken from all over Indiana. It contains approximately 35,000 boxes of core containing 51 miles of rock and sediments. The Core Repository is an asset to the citizens of Indiana and allows both geologists and the public to understand Indiana's geologic past and provide for its future. The Core Repository is open by appointment Monday through Friday, 8:30 a.m. to 4:30 p.m.
