Monte Verde, MOHN tay VAIR day, site is a prehistoric site in southern Chile that provides evidence that human beings inhabited the Americas before the Ice Age ended about 11,500 years ago. Using radiocarbon dating techniques, scientists determined that the site was inhabited by human beings at least 14,000 years ago. Archaeologists think the site may have been a camp used by people who lived by hunting, fishing, and gathering plants. The age of the site has forced scientists to reconsider earlier theories about how and when people first migrated to North and South America.
