It connects to a larger universe of ancient Texas burials, including the Buckeye Knoll site in Victoria County, where the earliest graves date to approximately 8,500 years ago, and where archaeologists uncovered one of the largest Early Archaic cemeteries in all of North America.

These are not isolated discoveries.

Together, they form the most complete picture yet assembled of who was living in Texas eight to ten thousand years ago — and the ancient DNA questions embedded in their bones have become central to understanding the deep human history of the continent.

The Plateau That Holds Its Dead

To understand why these discoveries matter, you need to understand the landscape where they happened.

The Edwards Plateau is a vast limestone upland occupying the heart of central and west-central Texas.

It covers roughly 24,000 square miles, an elevated table of rock tilted slightly toward the southeast, cut by river canyons on its edges — the Llano, the Guadalupe, the Pedernales, the Nueces.

Its surface is mantled in thin soil and cedar scrub, prickly pear, live oak.

Beneath the surface, the karst geology creates a hidden world of cavities, caves, and sinkholes formed over millions of years by the slow dissolution of limestone.

This landscape has been occupied by human beings for at least 13,500 years, possibly much longer.

The first inhabitants — the Paleoindians who entered the Americas as the great ice sheets retreated — moved through Texas pursuing mammoth, horse, giant bison, and other megafauna now long extinct.

Later, as the climate warmed and dried and the megafauna disappeared, the people adapted.

They became what archaeologists call Archaic hunter-gatherers: mobile, flexible, expert at reading the landscape, moving seasonally through territories they knew intimately, hunting deer and pronghorn and small game, harvesting plant foods, fishing the rivers.

It is these Archaic people — the hunter-gatherers who lived in Texas between roughly 10,000 and 2,000 years ago — whose remains have been preserved in the sinkholes and caves of the plateau.
