A new four-part PBS docuseries, "Native America," seeks to recreate a world in the Americas generations prior to the arrival of Europeans.
Using archaeology, Native American oral traditions, even high-tech 3D renditions, the series presents images of busy cities connected by networks that span from the present-day United States to South America.
The docuseries shows how Chaco Canyon in New Mexico became a busy spiritual and commercial center centuries before New York was founded.
It also discusses the pyramids of Teotihuacan, Mexico and how 10,000 people helped erect massive earthwork pyramids outside present-day St. Louis.
Series executive producer and director Gary Glassman said the project took more than a year to plan because producers wanted to make sure they had buy-in from Native American communities the documentaries sought to cover.
