Avery Island is not really an island – it is a huge dome of rock salt, three miles long and two and a half miles wide. At it's highest point it is only 152 feet above sea level. It is located seven miles south of New Iberia, surrounded by wet marsh and the Bayou Peiti Anse. It’s one of five along the Louisiana Gulf Coast, formed when an ancient seabed evaporated, depositing pure salt, which rose up in large chunks and pushed the ground into a hill.

Long before its namesake Avery family settled there in the 1830s, American Indians discovered that Avery Island’s verdant flora covered a precious natural resource—a massive salt dome. There the Indians boiled the Island’s briny spring water to extract salt, which they traded to other tribes as far away as central Texas, Arkansas, and Ohio.
