hi diana: i used to swim in the hole that the stone came from named the "empire quarry" that was before bathing suits were invented--at least we didn't know there was such a thing! the scientific name of indiana limestone is "oolite" therefore, the origin of the name oolitic. my wife graduated from oolitic high school in 1959. i believe there were less than 20 in her class. keep up the good work! allen murray, list adm.
