The Prehistoric Indian Village is the only active archeological site in South Dakota that is open to the public. It was occupied over 1,000 years ago by Native Americans who lived in earthen lodges.

Lora Perkins, associate professor in South Dakota State University's Department of Natural Resource Management, is working with the National Park Service on a three-year, $900,000 project.

This October 10th is Native Americans' Day. Head west to South Dakota to watch parades and Native American dancing. Dig for arrowheads and watch as archeologists uncover important artifacts.
