Avery Island

Avery Island is a salt dome best known as the source of Tabasco sauce. Located in Iberia Parish, Louisiana, United States, it is approximately three miles inland from Vermilion Bay, which in turn opens onto the Gulf of Mexico. A small human population lives on the island. The island is listed on the National Register of Historic Places.

The island was named after the Avery family, who settled there in the 1830s, but long before that, Native Americans had found that Avery Island's verdant flora covered a precious natural resource—a massive salt dome. There, Native Americans 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.
