Trump’s border wall construction threatens rock art as old as the pyramids: ‘The ancestors are still here’

The brief

Rock art is imagery made directly on natural stone, rather than on a separate canvas. These paintings preserve ancient ideas, stories, and creative choices across thousands of years. The article describes them as the oldest-known books in North America. At a west Texas cave, archaeologist Carolyn Boyd studied three enormous human-like figures painted on a rock wall. The murals may be about 4,000 years old, and a rock overhang sheltered them from weather. Ancient artists likely ground minerals into pigments. They mixed those colors with a binder, then applied them by hand or through a simple spray technique. That protection explains why the images remain visible today. Their survival is now uncertain because the president’s proposed border wall could damage or destroy them. Documenting and protecting these sites matters because damaged stone images may lose details and meaning forever.

What is rock art, and how were these ancient murals made?

Rock art is imagery made directly on natural stone, rather than on a separate canvas. These paintings preserve ancient ideas, stories, and creative choices across thousands of years. The article describes them as the oldest-known books in North America.

At a west Texas cave, archaeologist Carolyn Boyd studied three enormous human-like figures painted on a rock wall. The murals may be about 4,000 years old, and a rock overhang sheltered them from weather. Ancient artists likely ground minerals into pigments. They mixed those colors with a binder, then applied them by hand or through a simple spray technique.

That protection explains why the images remain visible today. Their survival is now uncertain because the president’s proposed border wall could damage or destroy them. Documenting and protecting these sites matters because damaged stone images may lose details and meaning forever.

02

How old are the murals, and how do archaeologists know their age?

The murals are about 4,000 years old, making them among North America’s oldest surviving large-scale records. Archaeologists do not rely on appearance alone; they combine direct testing with clues from the surrounding site.

At a west Texas cave, Carolyn Boyd studied three towering human-like figures beneath a protective rock overhang. Researchers can date organic material in paint, including charcoal or other carbon-based binders, using radiocarbon analysis. They also compare the paintings with dated layers and artifacts, checking whether the results fit the artwork’s style and position.

That evidence places the paintings roughly four millennia ago, though exact dates can vary. The overhang helped preserve them, but proposed border construction could damage or destroy this irreplaceable record. Careful documentation and protection matter because these images preserve knowledge from communities living in North America long before written books.

03

Where are the paintings located, and how close would the proposed border wall be to them?

The paintings are ancient murals in caves and rock shelters across west Texas’s Lower Pecos Canyonlands. They preserve Indigenous stories and images created roughly 4,000 years ago.

Archeologist Carolyn Boyd studied these murals, including towering human-like figures painted beneath a protective rock overhang. Proposed border-wall construction could threaten them through nearby building, roads, vibration, and landscape disturbance.

The wall would not necessarily cross every painting site. However, some proposed sections could stand only a few hundred feet away. That distance makes construction activity a practical concern, even when the artwork sits inside a cave. The paintings’ age and fragility also make damage difficult or impossible to repair. Their location near the Rio Grande places them within a border zone where security projects could affect archaeological evidence. Protecting them would require careful surveys and changes to planned construction routes.

04

What parts of the border-wall construction could damage or destroy the paintings and the caves that protect them?

Construction would threaten more than the wall itself. Clearing land, building access roads, drilling foundations, and moving heavy equipment could damage caves and their paintings.

At a west Texas cave, Carolyn Boyd examined three huge human-like figures beneath a protective overhang. They may be about 4,000 years old. Vibration, dust, runoff, or altered drainage could harm the rock surface or shelter protecting it.

The proposed project’s footprint could include roads, lighting, security facilities, and the wall itself. Because the paintings survived beneath an overhang for millennia, changing that shelter could expose them to weather. The article presents these sites as irreplaceable records. Once a painted surface or cave is destroyed, its information cannot be recovered. The concern is therefore the entire construction zone, not merely the finished barrier.

05

Why are these murals described as some of the oldest-known books in North America?

They are called “books” because the paintings preserve knowledge and stories without using written pages. Their images let people study how earlier Indigenous artists recorded ideas, beliefs, and experiences. That makes the cave a cultural archive, not merely a decorated rock shelter.

At a west Texas cave, three enormous human-like figures rise toward an overhang. Carolyn Boyd, an archeologist at Texas State University, examines murals that may be about 4,000 years old. The overhang protected the paintings from weather, allowing their visual message to survive across many generations.

That survival is now at risk. The president’s proposed border wall could damage or destroy these murals and other archaeological sites. Protecting them matters because erased images would remove a rare record of North American history. Researchers would also lose evidence about the people who created them.

06

Which Indigenous communities and government agencies have a role in protecting these sites?

The passage identifies no specific Indigenous community or government agency by name. Therefore, it cannot support a reliable list of official partners. Descendants of the artists have a direct cultural connection, while government responsibility depends on land ownership and border authority.

One documented example is Carolyn Boyd, an archeologist at Texas State University. She examined three huge human-like figures painted on a west Texas cave wall. The overhang protected them from weather for perhaps 4,000 years, but border construction could damage or destroy such sites.

For the communities and agencies involved, the supplied excerpt is incomplete. It names Boyd and Texas State University, but no tribe, land-management agency, or border agency. The full article is needed before assigning roles, including consultation, monitoring, or construction limits.

07

Why is preserving archaeological evidence important for understanding societies that left few or no written records?

Archaeological evidence can act like a record when a society left no writing. It preserves information about beliefs, daily life, skills, relationships, and practices that written histories may omit or never record. Careful study of pigments, figures, tools, and locations can connect discoveries, revealing how people used their surroundings and what they valued.

In west Texas, archeologist Carolyn Boyd examined cave murals painted perhaps 4,000 years ago. Three massive human-like figures stretch toward an overhang that sheltered them from the elements. Their survival gives researchers clues about artistic ability, shared meanings, and community life, even without written explanations.

The source warns that a proposed border wall could damage or destroy these “oldest-known books in North America.” Once paintings or their surrounding layers are damaged, researchers lose evidence and context together. Preserving sites protects irreplaceable knowledge and keeps future researchers able to ask new questions.
