When most people think of "ancient American civilizations," the Aztec, Maya, or Inca cultures probably come to mind immediately, because the societies in Mesoamerica and South America left behind permanent structures for millions of visitors from around the world to see each year. But in fact, there were people inhabiting the region over 11,000 years earlier.
The discovery of distinct arrow tips throughout the United States, Canada, and parts of northern Mexico in the early 20th century, often referred to by archaeologists as projectile points, is a testament to the success of the Paleolithic culture, now known as Clovis. Modern scholars point to the extensive nature of Clovis archaeological sites as proof of its importance, yet these same scholars have only begun to uncover this culture, and as they do, more questions are raised than there are answers. Although most of the questions are not controversial, some of the answers scholars have forwarded are. Any examination of the Clovis culture begins with what is known. Archaeologists know the approximate chronological and geographic range of the Clovis culture, and they can identify what made the Clovis people unique. These were the projectile points the Clovis people made, setting them apart from most people that came before and after them
In North America, from about 1000-1500 CE, an equally complex culture formed along the banks of the Mississippi, Missouri, and Ohio Rivers. From Red Wing, Minnesota to Greenhouse, Louisiana, and from Spiro, Oklahoma to Macon, Georgia, societies built impressive mound structures that served as ritual platforms, burial sites, and residences for the elites. These mounds also served as the focal points of urban areas of varying sizes that were connected to each other through trade and ideology, forming a culture that modern historians have since designated the "Mississippian culture."
