Artifacts left behind by the Ancestral Pueblo people, often called “Anasazi” in older literature, span everything from intricately painted pottery and turquoise jewelry to the skeletal remains of tropical macaws that had no business being in the high desert of the American Southwest. Taken together, these objects paint a picture of a society far more connected, stratified, and ritually complex than the “cliff dweller” stereotype suggests. The term “Anasazi” itself, though, carries baggage that shapes how these artifacts are studied, displayed, and returned to descendant communities today.
Why the Name “Anasazi” Is Fading From Use
If you search for “Anasazi artifacts,” you will find the term everywhere, from museum gift shops to national park brochures printed decades ago. The word comes from a Navajo (Diné) term that has been variously translated as “ancient ones,” “ancient enemies,” or “ancestors of our enemies.” Many Pueblo people, the living descendants of the civilization in question, prefer not to use a Navajo-derived name for their own heritage. Archaeologists and federal agencies have largely shifted to “Ancestral Pueblo” or “Ancestral Puebloan” to better reflect the connection between the ancient builders and today’s Hopi, Zuni, Acoma, and other Pueblo communities. For clarity, this article uses “Ancestral Pueblo” except where discussing older literature that uses the other term.
Pottery as the Signature Artifact Class
Ceramics are the single most abundant and widely studied artifact type from Ancestral Pueblo sites, and for good reason. Pottery survives well in the arid Southwest, and its styles changed over time in ways that let archaeologists build detailed timelines. Black-on-white designs, where dark mineral or carbon-based paint was applied over a white or gray slip, are the hallmark of the tradition. Regional variants are distinctive enough that specialists can often pin a sherd to a specific area and century.
One particularly interesting ceramic form is the handled mug associated with the Mesa Verde region. A study of nearly 500 of these mugs found that they appeared primarily between roughly 1100 and 1300 CE, took on a variety of shapes (most commonly a truncated cone), and showed a fairly uniform size range, suggesting they were made for a consistent purpose rather than being freeform artistic expressions. While most turned up in the Northern San Juan area, dozens were found at sites well outside that region, indicating that the mugs or the people who made them traveled.
Even more striking are the cylinder jars concentrated at Pueblo Bonito in Chaco Canyon. These tall, narrow vessels are rare across the broader Southwest but appeared in caches at Chaco, hinting at a specialized function. Chemical analysis of residues inside fragments of these jars detected theobromine, a compound found in cacao, revealing that people at Chaco were drinking chocolate-based beverages around 1000 to 1125 CE. Since cacao does not grow anywhere near New Mexico, the beans had to travel from tropical Mesoamerica, hundreds of miles to the south.
Cacao, Holly, and Ritual Drinking
The cacao discovery at Pueblo Bonito was the first confirmed evidence of cacao use north of the present-day Mexican border, and it upended assumptions about how isolated the Ancestral Pueblo world was from Mesoamerican cultures like the Maya and the Toltecs.1Proceedings of the National Academy of Sciences. Evidence of cacao use in the Prehispanic American Southwest But chocolate was not the only caffeinated drink in circulation. A large-scale follow-up study of organic residues from archaeological sites across the Southwest and Mexican Northwest found widespread evidence of two different caffeinated plants: cacao and holly. Holly-based drinks, similar to the “black drink” historically documented among Southeastern peoples, appear to have been consumed at communal, ritual gatherings alongside or instead of cacao.2Proceedings of the National Academy of Sciences. Ritual drinks in the pre-Hispanic US Southwest and Mexican Northwest
The implication is that certain Ancestral Pueblo ceremonies involved stimulant beverages that required long-distance trade to obtain. These were not casual kitchen items. The cylinder jars that held the cacao at Pueblo Bonito were deposited in ritual caches, and the beverages themselves were likely consumed in controlled, communal settings rather than as everyday refreshments. The artifacts, in other words, are evidence not just of trade but of shared ceremonial practices spanning a huge geographic area.
Turquoise and Its Trade Routes
If pottery is the most common Ancestral Pueblo artifact, turquoise is arguably the most glamorous. Tens of thousands of turquoise beads, pendants, and mosaic pieces have been recovered from Chaco Canyon alone. The stone was clearly precious: caches of turquoise at Pueblo Bonito include pieces numbering in the hundreds of thousands of individual beads. But where did all that turquoise come from?
Isotopic analysis of 74 turquoise artifacts from Puebloan sites in the San Juan Basin and from outlying areas in southern Utah and southern Nevada identified multiple distinct source areas. Some turquoise matched deposits along the Rio Grande Rift, relatively close to Chaco. Other pieces traced to resource areas in Nevada and the Mojave Desert of southeastern California, hundreds of miles to the west.3Journal of Archaeological Science. Turquoise trade of the Ancestral Puebloan: Chaco and beyond The geochemical fingerprints pointed to multiple trade routes feeding into Chaco Canyon, and the data supported a role for the Virgin Puebloan communities in moving turquoise, shell, and salt eastward into the San Juan Basin. Chaco was not simply receiving turquoise from one nearby mine; it sat at the hub of a web of exchange relationships stretching across the entire desert West.
What makes this particularly interesting is that turquoise, unlike pottery, does not break down and re-form locally. Each piece carries the chemical signature of the geological deposit where it formed, so researchers can trace individual artifacts to their origin with surprising precision. The picture that emerges is of a society that invested enormous effort in acquiring a single blue-green stone, presumably because of its ritual and social significance.
Scarlet Macaws in the Desert
Few Ancestral Pueblo artifacts are as immediately arresting as the skeletal remains of scarlet macaws found at Chaco Canyon and other sites. Scarlet macaws are tropical birds native to the lowland forests of Mexico and Central America. They have no wild range anywhere near the Colorado Plateau. Yet their bones, and sometimes their feathers preserved in dry cave deposits, turn up at sites throughout the region.
Radiocarbon dating of macaw skeletons from Chaco Canyon showed that the earliest birds arrived between about 900 and 975 CE, earlier than most researchers had expected. Previous models tied the procurement of exotic macaws to Chaco’s peak period of monumental construction in the eleventh century, but most of the directly dated birds actually predate that building boom. The researchers who carried out the dating proposed that access to these striking tropical birds was linked to the early development of social hierarchy at Chaco, not a later byproduct of it.4Proceedings of the National Academy of Sciences. Early procurement of scarlet macaws and the emergence of social complexity in Chaco Canyon, NM In other words, controlling rare, impressive goods from far away may have been one of the mechanisms through which certain families or leaders consolidated power.
A follow-up genomic study added another layer. DNA extracted from macaw bones at Southwestern sites dating between 900 and 1200 CE revealed extremely low genetic diversity: all the birds belonged to a single mitochondrial lineage out of the five historically known in the wild population.5Proceedings of the National Academy of Sciences. Archaeogenomic evidence from the southwestern US points to a pre-Hispanic scarlet macaw breeding colony That kind of bottleneck is exactly what you would expect if the birds were being bred in captivity from a small founding stock rather than captured individually from wild flocks. The most likely explanation is that a breeding colony existed somewhere in the borderlands between the Southwest and Mesoamerica, specifically to supply Pueblo communities with live macaws and their brilliantly colored feathers. These were not random curiosities; they were deliberately produced luxury goods embedded in a continental-scale exchange system.
Timber and What Tree Rings Reveal
The great houses of Chaco Canyon contain an estimated 200,000 or more wooden beams, and those timbers are artifacts in their own right. Tree-ring analysis has long been the backbone of Southwestern archaeology, providing calendar-year dates for construction events. But a newer application goes further: using the width patterns of the rings to match each beam to the mountain range where the tree grew, effectively sourcing the lumber.
A study that applied this technique to 170 timbers from seven Chaco great houses found that roughly 70 percent of the wood came from the Chuska Mountains and the Zuni Mountains, both more than 75 kilometers away. Before about 1020 CE, nearly all the timber came from the Zuni Mountains, a source that had not previously been recognized. By 1060 CE, the Chuska Mountains had overtaken the Zunis as the primary supplier.6PubMed Central. Eleventh-century shift in timber procurement areas for the great houses of Chaco Canyon That shift is significant. It suggests that the political or economic relationships connecting Chaco to outlying communities changed over time, and that the labor and logistics required to move thousands of heavy logs across dozens of miles of roadless terrain were organized and redirected as those relationships evolved.
The timber findings align with other evidence for centralized coordination at Chaco. The canyon itself has limited arable land and limited water, yet it supported massive architecture. The beams, like the turquoise and the macaws, point to a system in which resources flowed inward to Chaco from a wide periphery, likely organized through a combination of tribute, trade, and ritual obligation.
What the Artifact Record Tells Us About Social Complexity
One of the biggest shifts in how researchers interpret Ancestral Pueblo artifacts over the past few decades is the move away from viewing these societies as simple, egalitarian farming villages. The evidence increasingly points to significant social stratification, at least at Chaco Canyon during its peak. Exotic goods like macaw feathers and cacao drinks were not distributed evenly across the population. They clustered in specific rooms and ritual contexts at Pueblo Bonito, suggesting that access was controlled by particular groups or individuals.
Turquoise workshops have been found at Chaco where raw stone was worked into finished beads and ornaments, indicating that the production process itself was concentrated there rather than being a household-level activity carried out everywhere. The sheer volume of turquoise in certain burial and cache contexts dwarfs what is found at outlying sites, reinforcing the interpretation of Chaco as a central place that accumulated prestige goods.
At the same time, not all Ancestral Pueblo communities operated like Chaco. Mesa Verde, for example, shows a different pattern: more dispersed settlement, less evidence of massive inflows of exotic materials, and artifact assemblages that suggest a more household-oriented economy. The handled mugs characteristic of the Mesa Verde region, while sometimes found at distant sites, do not show the same extreme concentration as Chaco’s cylinder jars or turquoise caches. The Ancestral Pueblo world was not monolithic, and the artifacts from different regions tell different stories about how people organized their lives.
Looting, Collection, and the Damage Done
The story of Ancestral Pueblo artifacts cannot be separated from the history of how they were removed from the ground. Beginning in the late nineteenth century, amateur collectors and early archaeologists excavated sites across the Southwest with little concern for context or for the wishes of Indigenous peoples. Pueblo Bonito was dug by the Hyde Exploring Expedition in the 1890s, and the objects removed during that era ended up in museum collections far from their origin. The damage went beyond the loss of objects: removing artifacts without careful recording of their position destroyed the spatial relationships that give those objects meaning. A turquoise bead in a museum drawer tells you far less than a turquoise bead recorded in situ alongside a macaw skeleton and a cylinder jar.7Science. When collectors came for the American West Sins of the Shovel: Looting, Murder, and the Evolution of American Archaeology
Pot hunting, the illegal excavation of sites for saleable artifacts, remained a serious problem throughout the twentieth century and continues today. The dry conditions that preserve Ancestral Pueblo artifacts so beautifully also make them appealing to collectors. Whole pottery vessels in good condition can fetch thousands of dollars on the black market. Every looted site is a dataset destroyed: the vessels are ripped from their archaeological context, and whatever they could have told us about the people who made and used them is lost.
Repatriation and Tribal Stewardship
The passage of the Native American Graves Protection and Repatriation Act (NAGPRA) in 1990 fundamentally changed the relationship between museums, archaeologists, and tribes when it comes to Ancestral Pueblo artifacts. NAGPRA requires federally funded institutions to inventory their holdings of Native American human remains, funerary objects, sacred objects, and objects of cultural patrimony, and to consult with affiliated tribes about returning them.8Annual Review of Anthropology. NAGPRA at 30: The Effects of Repatriation
Implementation has been uneven, and the process can be slow and contentious. Determining cultural affiliation, the connection between a modern tribe and an ancient site, is straightforward in some cases and deeply complex in others. In one instructive example, the White Mountain Apache Tribe worked with the Hopi, Zuni, and the Western Apache NAGPRA Working Group to develop a geography-based cultural affiliation assessment for sites on the Fort Apache Reservation. The project combined archaeological data with information provided by tribal representatives about sacred landscapes and oral traditions linking people, places, and history. The result was a set of specific recommendations for intertribal repatriation and reburial, as well as broader guidelines for heritage stewardship that shifted the focus from artifacts as stand-alone objects to artifacts as part of living cultural landscapes.9Journal of Social Archaeology. Putting patria back into repatriation
For descendant communities, these artifacts are not curiosities or data points. They are the material traces of ancestors, and their treatment carries moral weight. The tension between scientific study and tribal sovereignty remains real, but the direction of change over the past three decades has been toward greater collaboration, with tribes playing an increasingly active role in deciding how their heritage is studied, stored, and displayed.
Artifacts Still in the Ground
Only a fraction of Ancestral Pueblo sites have been professionally excavated. Thousands of sites across the Four Corners region are documented but unexcavated, and many more remain unrecorded. The arid climate of the Southwest is unusually kind to organic materials. Wooden objects, woven textiles, cordage, sandals, and even food remains survive in dry rock shelters and sealed rooms in ways they rarely do in wetter environments. Every year, erosion, wildfire, and unauthorized digging expose or destroy material that has sat undisturbed for centuries.
Modern archaeology increasingly avoids full excavation in favor of non-invasive methods. Ground-penetrating radar, aerial lidar, and chemical analysis of surface soils can reveal buried structures and activity areas without turning a shovel of dirt. When excavation does happen, it tends to be limited in scope and driven by specific research questions rather than the “dig everything” approach of earlier generations. The philosophy has shifted: the ground is the best storage facility these artifacts will ever have, and leaving them in place preserves the context that makes them scientifically and culturally meaningful. For researchers, the challenge is extracting as much information as possible while disturbing as little as possible. For descendant communities, the challenge is ensuring that the sites and their contents are protected not just from looters but from well-meaning researchers whose priorities may not align with tribal values.
Advances in residue chemistry, ancient DNA extraction, and isotopic sourcing mean that even small, unpromising-looking artifacts can yield information that would have been unimaginable a generation ago. A pottery sherd can reveal what was cooked or stored in it. A fragment of bone can identify the species, the geographic origin of the animal, and whether it was wild-caught or captive-bred. A turquoise bead can be traced to a specific mine. The artifacts themselves have not changed, but the questions we can ask of them have expanded enormously, and that expansion shows no sign of slowing down.
