American archaeology is a discipline in constant flux. Over the last half-century, conventional attitudes about the arrival of humans in North America have undergone repeated shifts, with estimates of the earliest human activity continually pushed back to more distant times.
However, discoveries stemming from one controversial archaeological site in the American Southeast, if confirmed, could extend present timelines for human arrival in the New World by several tens of thousands of years, adding to a growing number of findings in recent years that are reshaping our understanding of the early Americas.
The First Americans
For many decades, the long-established chronological marker for America’s first arrivals centered on discoveries made near Clovis, New Mexico, including expertly crafted “fluted” spear points and other artifacts, which served as the type site for America’s earliest definitive cultural manifestation. The resulting “Clovis First” theory reigned for most of the 20th century, arguing that America’s first inhabitants made their way across an ice-free Beringian land corridor somewhere around 13,000 years ago.
However, by the 1970s, a new phenomenon in American archaeology had begun to emerge: sites suggesting that even earlier arrivals may have occurred. With time, locations like Meadowcroft Rock Shelter in Washington County, Pennsylvania, the Monte Verde site in Chile, and several others in North and South America would carry the idea of a “pre-Clovis” presence in the Americas from being an anachronistic gadfly for archaeologists, to eventually becoming an accepted reality.
Today, more recent discoveries, including ancient human fossil footprints at sites like White Sands in New Mexico, have extended the now well-accepted earlier-than-Clovis timeline even further back, with confirmed dates revealing a human presence there by as early as 21,000 to 23,000 years ago. This, along with growing genetic evidence, new models of possible coastal migration routes, and other data, continues to help archaeologists assemble a broader picture of America’s first inhabitants and a far deeper timeline for their arrival than most would have ever expected.
Yet while discoveries like those at White Sands unequivocally demonstrate a human presence in the Americas by around 23,000 years ago, there are still other sites that challenge even those remarkably early dates for human arrivals in the New World—dates which, if ever confirmed, would introduce even greater challenges to our existing knowledge of the ancient Americas.
The Topper Site
Few other proposed pre-Clovis archaeological sites have aroused as much controversy as the Topper Site in Allendale County, South Carolina.
An ancient chert quarry, the site was initially identified by Albert Goodyear, Ph.D., now a semi-retired professor of archaeology at the University of South Carolina, more than four decades ago. During the late Pleistocene American Paleoindian period, some of America’s earliest inhabitants relied on the abundant Allendale Coastal Plain chert rock nodules at the location for crafting ancient stone tools, which included the distinctive fluted projectiles now associated with the Clovis cultural manifestation.
