depictions of llama caravans, possibly marking a
ceremonial site for
caravaners passing through the mountains.

Trade caravans, whether supported by mules, camels or llamas, have helped archaeologists piece together the past in many corners of the world.
Hundreds of years before the Inca road system connected a sprawling empire, a more modest network of trails linked the small communities that lined the mountains and coastlines of South America. These trails, snaking through the Andes, supported a vibrant network of llama caravans, which may have been the driving force behind elements of cultural continuity that have been shared by different South American societies for the last millennium—and perhaps even longer.

Hundreds of years before the Inca road system connected a sprawling empire, a more modest network of trails linked the small communities that lined the mountains and coastlines of South America. These trails, snaking through the Andes, supported a vibrant network of llama caravans, which may have been the driving force behind elements of cultural continuity that have been shared by different South American societies for the last millennium—and perhaps even longer.
“These caravanners were the lubricant for more than just trade goods,” says Nicholas Tripcevich, a research associate and lab manager at the University of California, Berkeley. “They served an important role linking people. They probably spread information, stories.”
Caravans have moved goods and news across deserts and mountains by donkey, mule and camel throughout the history of civilization. The role these merchants played in Arabia and Europe in centuries past is well known, but nomadic traders also connected ancient South American cities and civilizations. While traveling vendors in other parts of the world may have used horses or wagons to transport goods, the caravans of South America made use of llamas and alpacas, native to the area and built for mountainous terrain.
The first evidence in the Andean region of caravans using camelid species, including llamas and the woollier alpacas, dates to around 3,000 years ago. Traces of ancient trails and scattered archaeological deposits have been discovered in modern Chile, south of the Atacama Desert. But our knowledge of South American caravanners is limited, largely due to the fact that the itinerant nomads left little trace of their presence in the archaeological record other than hints of the weather-worn trails they followed.
However, a new analysis of rock art
depicting caravans found in a rocky outcropping above a valley in
northern Chile, as well as the bones of llamas whose meat may have been
offered in ritual sacrifice, reveals a snapshot of the hidden ceremonial
lives of these elusive traders. The caravanners, who offered one of the
only ways to communicate across great distances, may have held
disparate communities together during a period of instability about 900
years ago.
“The caravanners were grand cultural connectors in the Andes,” says Daniela Valenzuela, an anthropology professor at the University of Tarapacá in Chile and lead author of a study published recently in Quaternary International that analyzes the caravan site in Chile. She compares the South American llama drivers who stopped at the site, known as Cruces de Molinos, to the caravan traditions of other parts of the world.
The caravan travelers who drew the rock art and left offerings at Cruces de Molinos were likely alive during a period that lasted several centuries with no major regional empires. Earlier cultures like the Tiwanaku, which controlled parts of modern-day Bolivia, northern Chile and Peru, had abruptly collapsed by about 1000 AD. The Inca, for their part, began to muster strength in the 13th century but didn’t arrive in northern Chile until about 1400.
While these larger empires had the resources to move trade goods, sometimes paid as tribute, Valenzuela says that the period between these major empires was characterized by smaller communities without the reach of the Inca or Tiwanaku. As a result, caravans must have played a critical role moving goods between the coasts, fertile valleys and highlands.
“They traded ch’arki, meat, textiles or wool, and they exchanged highland items with maize, fish and coastal items like guano to fertilize the plants,” Valenzuela says. (Ch’arki is a Quechua word for dried meat, later anglicized as “jerky.”)
The Cruces de Molinos site sits above the Valley of Lluta and a small town, on the border of the lush pastures of the highlands where llamas and alpacas would have had plenty of water and grass. Valenzuela says that the fact that the area marked a transition between climates and ecological zones may have also been why the caravanners chose the spot to make ceremonial offerings.
Valenzuela discovered the rock art while doing a survey in 2000 as part of her bachelor’s thesis. While she found about 10 different sites with rock art, she says that Cruces de Molinos, about 500 feet above the valley floor, is the most elaborate. The art, which was likely made between 950 and 1400 AD, depicts a number of different scenes, including people leading camelids along by a rope or string. Some parts of the illustrations also depict the large, ostrich-like rhea, which often shares pastures with camelids in the area.

“We suppose these images represent the caravanners’ desires,” she says, adding that they may have been a wish for safe journeys and good trade. Meanwhile, nearby camelid bones dating from 1060 to 1190 AD show cut marks and cross sections of animal parts, indicating the meat was likely butchered and prepared as jerky.
While these remains may represent a cache of food stored for later times, Valenzuela believes their placement beneath an engraved block of stone indicates that they were left as a type of spiritual offering, possibly to Pachamama—a goddess who represents concepts like earth, time and fertility. The suspected offering of llama meat, along with the rock art and the high, relatively inaccessible placement of the site all indicate that this area was used as a ceremonial pit stop. Caravan traders may have departed from nearby trade routes, whose traces can still be seen on the landscape, to make offerings and perform rituals before embarking on the next leg of their journey.
Tripcevich, who was not involved in the new research, has worked with contemporary caravanners in South America. In 2007, he followed a caravan through Peru for two weeks to learn more about long distance travel strategies. The caravan, which hadn’t traveled this route since 1994 when new roads were built, loaded up on salt from the mines around Cotahuasi on the coast of Peru and transported it to the Apurimac area to the north. While there is some cultural continuity between the ancient and the modern caravanners, Tripcevich says he isn’t sure today’s caravanners descend directly from the people who left rock art and offerings at Cruces de Molinos.
