Lower Pecos

The Lower Pecos is one of the most distinctive and significant archeological regions in Texas. It is not that the Indians who once lived here were particularly important—they were just ordinary folk like many others all across the landscape of prehistoric Texas. But due to a unique combination of geological and ecological factors, the jagged canyonlands they called home contain an extraordinarily rich cultural legacy of ordinary and extraordinary things that are rarely found in most other areas of North America—perfectly preserved food remains, vivid rock art over 4,000 years old, grass-lined beds, painted deer bones, and much more. By studying these things and the places where they are found, researchers from many disciplines—archeologists, anthropologists, biologists, art historians, paleontologists, geologists, and others—are piecing together a remarkably detailed understanding of the human and natural past.

Although the Lower Pecos contains a uniquely vital cultural legacy of worldwide importance, many Texans don't even know it exists. Sadly, among those who do are some who rip apart its caves out of greed and stupidity and crudely carve their names on ancient works of art. Those who explore this exhibit will understand how senseless and tragic these thoughtless actions are. Perhaps as more people appreciate what can be learned about the cultural heritage of Texas in this unparalleled place, the sites that remain unharmed will be protected for the future.

This is the first of several interrelated exhibits on the Lower Pecos and its remarkable archeological record that will appear in Texas Beyond History. Its purpose is to provide an overview of the region and introduce some of the places and topics that will be explored in depth in other exhibits to come. The companion exhibit on one of the most amazing and best known archeological sites in the Lower Pecos—Bonfire Shelter—serves as a demonstration of what can be and has been learned by thoughtful study.

Over the next few years other online exhibits will be created on archeological sites and themes unique to the Lower Pecos area. Some of the exhibits will be based on information collected prior to the filling of Amistad Reservoir, the huge lake that now fills many of the canyons in Texas and Mexico that lie at the heart of the Lower Pecos. These exhibits will be developed in partnership with the Amistad National Recreational Area of the National Park Service (ANRA-NPS). Other exhibits will be developed in partnership with researchers at Texas A&M University and elsewhere who are experts in the archeology, ecology, and rock art of the Lower Pecos. Come back and visit from time to time and see what is new.

What is the Lower Pecos Archeological Region?

Archeological regions are areas that are distinct in the minds of archeologists because of the similarities they observe in artifacts, geography, climate, and other interwoven factors. In some areas of the state, archeological regions are very broad and cover many hundreds of square miles—the Caddo area, for example, covers much of northeast Texas and adjacent areas of neighboring states. In contrast, the Lower Pecos archeological region covers a much smaller territory—the area surrounding the junctions of the Pecos and Devils Rivers with the Rio Grande just upstream from Del Rio, Texas. Although the best-known part of this area lies in Texas, the Lower Pecos archeological region extends southward into northern Coahuila, Mexico.

The three rivers and their many tributaries form deeply incised canyons within which numerous rockshelters occur. Although the region is arid, averaging less than 15 inches of rain per year, the rivers as well as springs and temporary waterholes called tinajas within the smaller canyons provided reliable water sources. For over 13,000 years prehistoric hunter-gatherers lived in the region, sometimes occupying the rockshelters. The generally dry conditions coupled with the protected rockshelters resulted in the preservation of fragile materials such as wooden artifacts, woven sandals, and plant food refuse that decay quickly in most other areas of Texas.

But the most spectacular and defining archeological phenomenon in the Lower Pecos is the vivid rock art that adorns the protected walls of many of the rockshelters. The red, black, white, and yellow images created by hunter-gatherers in the Lower Pecos beginning as early as 5,500 years ago are among the best preserved rock art anywhere in the world. The art and archeology of the Lower Pecos is truly world class, providing archeologists with the opportunity to study the remains of prehistoric gathering and hunting cultures in far greater detail than is possible elsewhere in Texas and in much of the world.

The Natural World of the Lower Pecos is a curious place where permanent sources of water can be found a short walk from an arid landscape that may wait months or even years between periods of adequate rain. Each of the rivers—the Pecos, the Devils, and the Rio Grande—originate beyond, sometimes far, far, beyond the region, giving each a distinct character. Yet the rivers and their tributaries each form narrow ribbons of oasis-like abundance that twist and turn through the rocky and often waterless limestone terrain. Many of the plants and animals found here are at the outward limits of their distributions—the Lower Pecos lies at the intersection of ecological zones stretching north, east, south, and west.

Most of the evidence we have about the human past in the Lower Pecos comes from Rockshelters, natural shelters large and small that occur in great numbers within the rocky canyonlands of the region. Although it might seem that way, the prehistoric inhabitants of the region did not spend most of their lives in rockshelters. They lived throughout the canyons and high above in the uplands where grasslands once thrived. But, the rockshelters provided refuge during times of harsh weather and, more importantly for archeologists, the rockshelters protected the fragile remains left by prehistoric peoples from the ravages of time.

Above all else, the Rock Art of the Lower Pecos is its most distinctive and defining feature. The rockshelters and other protected rock surfaces provided the canvases upon which prehistoric and early historic-period Indian artists created some of the world's most remarkable "primitive art." While the cultures that produced the paintings and carvings may be considered primitive at least in a technological sense, the rock art is incredibly sophisticated and complex. Hundreds of different motifs and symbols occur representing at least four major styles, the earliest and best known of which, the Pecos River style, began perhaps 5,000 years ago.

The hunting and gathering Economy of the prehistoric peoples of the Lower Pecos can be studied in great detail due to the extraordinary preservation conditions. During most periods, plant gathering played a far more important role in the day-to-day diet than did hunting. While deer and buffalo were hunted whenever present, most game was rabbit-sized and smaller. The mainstay plants were lechugilla and sotol, two tough desert plants that have hearts (leaf bases) that are edible, but only after prolonged cooking. Such plants were none too desirable because they require an extraordinary amount of labor relative to the food yield. The fact that these plants were so important to the economy shows how difficult life could be, especially during droughts and other times of stress when few options were available.

Archeological excavations at more than a dozen rockshelters in the Lower Pecos have uncovered all sorts of Everyday, Extraordinary Things—trash, tools, food remains, medicine bundles, clothing and more. While many of these would have been ordinary, everyday things in the lives of the prehistoric Indians of the region, they are quite extraordinary in a different way. Most of them are made of fragile organic materials—wood and fiber—that are quickly destroyed by the passage of time in most places in Texas. Only in dry protected places (or in permanently waterlogged circumstances) are such everyday things preserved. Due to its unique setting, the Lower Pecos has yielded a wealth of such things and they shed much light on the prehistoric past.

Ironically, the Archeology of Lower Pecos is much less developed than that of many other areas of Texas despite its obvious importance and potential. To be sure, much has been learned, but there is still a great deal more research that is needed including further digging and further study of the evidence that already has been recovered. The first archeological expeditions in the 1930s were mounted by museums intent on gaining unusual materials for display. It was not until the late 1950s and early 1960s that serious research began, most of it prompted by the construction of a huge dam on the Rio Grande that flooded out the lower canyons of the Devils and Pecos Rivers.

The Before Amistad section tells the story of the archeological and paleoenviromental research that took place in advance of the completion of Amistad Reservoir.
