Limestone has shaped this area. Since before the turn of the century, limestone quarries have been extracting these blocks of stone and using them to build America. The Empire State building, New York's Grand Central Station, the Chicago Tribune tower, and the Biltmore in North Carolina are just a few of the many buildings constructed with the high quality limestone from this area. To get a taste for how limestone was and is currently extracted from beneath the ground, stop in at Elliott Special Products . Limestone continues to shape this area.
Caves dot the area.
Bluespring Caverns and Twin Caves at Spring Mill State Park both have boat tours back into caves. The blind cave creatures have become this way because near total darkness inside the caves gives them no use for eyesight. And there are stalactites and stalagmites. Besides the Twin Caves boat tour, Spring Mill State Park has lots of other things to see. They have a living pioneer village, working and looking as it might have in the early 1800s.
