DID Ep 2 - Ancient Snowbirds: How We Got the Shell Mounds

The shell mounds of Dauphin Island are among the oldest man-made features on the island—but they are not what they first appear to be.Built over generations by indigenous peoples connected to the Bottle Creek site in the Mobile-Tensaw Delta, these mounds are the accumulated remains of seasonal life along the Gulf Coast—layers of oyster shells, tools, and fire debris that reveal how people lived, adapted, and returned to this place year after year.In this episode, we explore the origins of the shell mounds, the people who created them, and the role Dauphin Island played as a seasonal refuge—what we might call, in a modern sense, an ancient “snowbird” destination.We also examine how these sites were later used for burial, diplomacy, and resource extraction, and how natural and human changes have reshaped both the island and the ecosystems that once made it so vital.This is the story of a place where memory, survival, and landscape come together—layer by layer.Key SourcesSaunders, Rebecca.
