Here come the humans!
Thousands of years ago, ancient peoples inhabited Louisiana.  They may have originally come across a frozen bridge of land between Asia and today's Alaska.  If so, they slowly settled in what would one day become the state of Louisiana.  

The bird-shaped mound at Poverty Point, in northeast Louisiana, is believed to be around 3,000 years old.  It is more than 70 feet (21 meters) high.  The early Louisiana culture is even older than South America's Mayas and Incas.  Artifacts found on Avery Island date back to 700 B.C.
