The Mound Builders were some of the most advanced Native peoples to be encountered by European explorers. They made their homes in the part of North America along what is now known as the Mississippi River. Their complex, ancient culture is very impressive: the Mound Builders are credited with being the first group of people to rely on farming as a major source of food. This book features photographs of cool artifacts and critical thinking questions to engage readers as they draw their own conclusions while learning about the Mound Builders.
