The island should not exist.

Mound Key was not deposited by glaciers or pushed up by tectonic forces. It was built, shell by shell, bone by bone, over more than two thousand years by the Calusa people. One hundred and twenty-five acres of land, created from the accumulated refuse of a civilization -- oyster shells, fish bones, pottery fragments, the compressed residue of countless meals and ceremonies. Carbon dating places the earliest human activity at the site to 1150 B.C., and what began as a low-lying oyster bar in the bay grew, generation after generation, into the capital of one of the most powerful indigenous kingdoms in pre-Columbian North America.
