Before Atascosa County: The People Who Learned the Land

The people we met in the last Before Atascosa County post weren’t the end of the story.

As the Ice Age faded, the climate and landscape changed, and so did the people living in it.

The Paleo-Indian people we met before were highly mobile. They moved through a much different South Texas landscape, following animals and other resources across a world that was still emerging from the Ice Age.

But that world was changing.

The large animals that had been important to earlier peoples became less available, while the plants, animals, and other resources of the developing South Texas Plains became increasingly important. The people living here adapted, not by simply stopping their movement, but by learning to make use of a much broader range of what the landscape offered.

Plants. Smaller animals. Deer. Rabbits. Fish. Shellfish. Nuts and seeds. Water. Stone.

The landscape itself became a resource map.

Imagine standing beside San Miguel Creek thousands of years ago.

The creek is still here, but almost everything else around you is different. There are no roads, houses, fences, power lines or towns. There is no Atascosa County.

There is only the creek, the surrounding land, the plants and animals living there, and a small group of people who know how to survive in it.

We have to be careful about imagining exactly what those people were doing at any particular moment. Archaeology doesn't give us a movie of their lives. It gives us fragments: stone tools, projectile points, campsites, food remains where they have survived, and the locations where people repeatedly used the landscape.

But those fragments tell us something important.

People knew this country.

They would have learned where water could be found. Where particular plants grew. Where animals were likely to be encountered. Which places offered useful stone. Which areas were productive at different times of the year.

They did not necessarily live permanently beside the creek. Instead, places with dependable resources could become places people returned to again and again.

And San Miguel Creek gives us a remarkable local connection to that story.

In 1968, archaeologist Thomas R. Hester documented prehistoric sites along San Miguel Creek in Frio, Atascosa, and McMullen counties. The sites recorded at the time contained a mixture of artifacts, but the assemblages were predominantly Archaic. The same creek where we found evidence of much earlier Paleo-Indian activity was also being used repeatedly by people thousands of years later.

The creek wasn't necessarily a destination in the way we think of a destination today.

It was part of a much larger landscape of places that people knew.

A group could move along the creek, establish a temporary camp, use the resources available there, and eventually move on. Another group could return later. And another generation could return again.

Over thousands of years, that kind of movement could create something more powerful than a single campsite.

It could create knowledge of a place.

And that knowledge wasn't limited to what could be found immediately around San Miguel Creek.

The people of the South Texas Plains were not isolated from the rest of the prehistoric world.

Archaeologists have found evidence of materials that originated far beyond South Texas. One of the most remarkable is obsidian, a volcanic glass that does not naturally occur in this region.

Obsidian is especially useful to archaeologists because its chemical composition can sometimes identify where the stone came from. And some obsidian found in the South Texas Plains has been traced to sources thousands of miles away.

There is even an obsidian dart-point fragment from Atascosa County.

Its exact geological source has not yet been identified, so we cannot say where that particular piece came from or exactly how it reached the county. But its presence is another reminder that the people living here were part of a world much larger than the creek valleys around them.

Archaeologists caution that, with so few identified obsidian artifacts in the South Texas Plains, it is difficult to reconstruct specific prehistoric trade routes. But the evidence does establish something remarkable: people living here had connections with people and places thousands of miles away. And physical objects weren't the only things that could travel. Ideas and information could travel, too.

So the story of the Archaic period isn't simply the story of people who survived after the Ice Age.

It is the story of people learning a changing world.

They learned when things appeared, where animals moved, which plants could be used, where water could be found, and where useful stone lay beneath the ground. The landscape was becoming something they knew intimately. And beyond San Miguel Creek, other people were doing the same thing, learning the places that sustained them.

The world they inhabited was enormous, but it was not empty.

It was connected.

Thousands of years before anyone drew a boundary around Atascosa County, people were already building relationships with this landscape and with one another.

They were learning the country.

And the story was only beginning.
