The bones came out, one by one, lifted from the earth by experienced hands, wrapped in foil and labelled, until the entire skeleton was liberated from this shallow gravesite. The coroners laid each package in a box. Someone unfurled a Maryland flag. Doug Bostick, executive director of the South Carolina Battleground Preservation Trust, offered words of thanks to the team.

“It’s so surreal,” he said of the find, “and real.”

Then his colleague David Reuwer voiced a loud cheer.

“Hip-hip …” he called.

“Hoozah!” came the collective response.

“Hip-hip …”

“Hoozah!”

“And for them, hip-hip …”

“HOOZAH!”

The box containing the remains of this Continental Army fighter from Maryland was carried slowly, in procession, to a nearby car as everyone gathered on this old battlefield stood respectfully, hand upon their chest.

The soldier, one of 14 discovered here in recent months, surely died a miserable death. His bones, and the skeletal remains of four others hastily buried next to him, were reminders of war’s terrible violence and time’s indifference.

These young men had been lost to the sandy soil, their determination in the face of an overpowering enemy largely forgotten. The battle is known, but not the individual fighters — men of the 1st and 2nd Maryland Brigades, the Delaware Continental Army, Armand’s Legion, and Virginia and North Carolina militias. This archaeological and forensic work changes that. The human remains, tattered though they are, will go to the lab of University of South Carolina anthropology professor Carlina Maria de la Cova for extensive analysis that surely will reveal new information about the Battle of Camden, a disaster for Continental Army Maj. Gen. Horatio Gates and the men under his command on that hot summer day of Aug. 16, 1780.

A project that began as an effort to remove artefacts and prepare a historic battlefield for public access became something else when the bones were discovered. Thirteen of the dead appear to have been artlessly buried before the wild hogs could get to them. The corpse of a British fighter was set deeper in the soil and formally laid out, perhaps by friends who took extra care. One of the 14 dead found here appears to have been a Native American who possibly was part of the North Carolina Royal Volunteers, a Loyalist militia unit.

Embedded in the broken bones were musket balls. In one set of remains found across Flat Rock Road, the lead ball lodged in the spine of a teenager, perhaps 14 or 15 years old. Archaeologists know this because of the growth plates visible at the ends of long bones. The boy with the shattered spine was one of at least two teenagers found during this dig. It’s highly unusual to exhume human remains from a historic battlefield, and even more unusual to find this many in one place, Bostick said. Generally, if bones are encountered, an effort is made to minimize activities that disturb them.

But this time, thanks to the expertise of forensic anthropologists from the Richland County Coroner’s Office and support from the Department of Natural Resources, the team determined to scrutinize their find in order to glean new information about the Camden killing field in which 3,700 Patriots and 2,230 British fighters and American Loyalists faced off. Plans already are afoot for a grand reinterment ceremony April 20-23. The bones will be returned to their original resting places, enclosed by pine caskets made in an 18th-century style and protected by vaulted graves.

The battle

By the time the dust cleared, some 1,900 men — more than half of the American forces — were dead or wounded. Perhaps 290 injured Patriots were taken, prisoner. Many of the rest, the inexperienced militiamen, had abandoned the battlefield so quickly, just a few suffered injuries. On the British side, about 70 men perished and 245 were wounded, representing about 15 per cent of Gen. Charles Cornwallis’ total forces.

The British had the advantage from the beginning. In May, they had finally captured Charleston, and to support the occupation of the city, Cornwallis established satellite garrisons, staging grounds and supply depots in the South Carolina backcountry, including a significant installation in Camden. Many of his fighters, therefore, were local, rested and ready for action.

Gates, determined to push the British out, marched his troops from Greensboro, N.C., starting that July. When Cornwallis heard about the approach of the Continental Army, he hastened from Charleston to Camden and organized his men.

The face-off was a mismatch, with experienced British regulars confronting a motley assortment of novice militiamen on one side of the battlefield. Gates’ men were hungry and tired; some were sick with dysentery. In the absence of proper rations and rum, they had been fed green peaches and molasses. When the militiamen threw down their arms, turned and fled, the Patriot side collapsed, though the Maryland and Delaware divisions attempted to hold their ground against the dominant British side.

Steven Smith, research professor at the University of South Carolina’s Institute of Archaeology and Anthropology, said he and colleague James Legg first started exploring the Camden battlefield with metal detectors in 1998. Over the years, they have found and plotted around 4,000 artefacts. During the COVID pandemic, they opted to spend much of the time in the open air with their equipment; it was an easy way to stay safe from the virus.

The site, several miles north of the city, was designated a National Historic Landmark in 1961 and placed on the National Register of Historic Places in 1966. The S.C. Battleground Preservation Trust secured nearly 300 acres and transferred ownership of the property to the Katawba Valley Land Trust in 2019. In September, the archaeologists started excavating for human remains. Collectors had told them about eight known burials. Legg found three sites; Smith found one. Then they encountered another, and another, until they had identified one double grave, one triple grave, one quintuple grave and four graves that each contained the bones of a single person.

“It was a disposal process,” Legg said. “The Continentals fought like Vikings in this battle, but they were overrun.”

It’s said that every battlefield is a burial ground. And there is little time for reverence.

The excavation

Bill Stevens, Richland County deputy coroner and a forensic anthropologist, is kneeling in the shallow gravesite with his two colleagues, Madeline Atwell and Rachel Baker. Loblolly pines tower overhead, but their spacing allows plenty of sunlight to reach the ground. A few flying bugs run accidentally into human obstacles.

The trio have exposed a cluster of five skeletons, digging delicately through the compact sand several inches beyond the bones that now are elevated atop earthen pedestals. Some of the appendages are intertwined and it’s difficult to determine which arm bone belongs to which individual. The dig looks like a miniature Bryce Canyon, except it wasn’t erosion that caused these formations, but an odd combination of human conflict and a researcher’s tiny spade.

The coroners already have removed nine sets of remains; this is the last gravesite to receive their meticulous attention. Gently, they insert the small blade between the sand pedestal and the skeleton, dislodging enough material to free the bone. These shallow burial sites have been disturbed over the decades by wild creatures, loggers, wagons, road workers and farmers. It’s remarkable that the skeletal remains are intact.

Inside this grave, archaeologists find more than bones. A beautifully made arrowhead, thousands of years old, is lodged in the sand. Several musket balls, the cause of injury and death, are clearly visible. Pewter buttons embossed with “USA” lay among the other objects.

The number of interested spectators is growing. Charles Baxley, chairman of S.C. American Revolution 250th commission has arrived, along with Bonnie Moffat, state regent of the Daughters of the American Revolution. Baxter is overseeing an ambitious project to educate residents and visitors about the war and the founding of the nation. The work here will become an important part of the commission’s narrative, he said.

“These are America’s first veterans, and these veterans were unceremoniously dumped into a hole,” he said.

Moffat said her organization is arranging to install perhaps 10 historic markers at battlefields across the state in conjunction with the 250th-anniversary celebration. Each marker costs about $4,800, she said. One is planned for Camden.

The S.C. Battleground Preservation Trust has been busy in recent years securing several properties and arranging for public access. It has been partnering with the nonprofit American Battlefield Trust, based in Washington, D.C., to develop the Liberty Trail, a network of Revolutionary War sites in South Carolina. A website, https://www.battlefields.org/learn/maps/liberty-trail, features details about the various historic confrontations and provides maps for those interested in visiting these sites. Now the trust is raising money, as much as $250,000, to help pay for the Camden project and reinterment events, Bostick said.

The reinterment

Battlefield archaeology is a relatively new field of study, Legg said. The first big project took place in 1984-85 at the site of Gen. George Armstrong Custer’s last stand at the Battle of Little Bighorn in Montana. A grass fire ignited by a tossed cigarette had exposed artifacts and inspired scholars to investigate the area, Legg said. They found a lot: spent cartridges, fired bullets, personal items and human remains.

In 1988, Legg and Smith performed excavation work at a Civil War battle site on Folly Island where they discovered, and removed, 19 sets of human remains, including what was left of the Black soldiers of the 55th Massachusetts Regiment who died there. This was one of the first formally organized Black units to fight on behalf of the United States. Legg and Smith arranged for a reburial at the Beaufort National Cemetery. The Camden battlefield now is well-marked with stakes indicating the top of the head and the bottom of the feet of each skeleton exhumed so archaeologists know precisely where the custom pine caskets sealed with hand-wrought nails are to lay, Smith said.

This will be no ordinary reinterment.

After about five months of study in the lab, the skeletal remains unearthed at the old battlefield will lie in state at the Kershaw-Cornwallis House from April 20 until the morning of April 22, Bostick said. On April 21, reenactors will set up an encampment by the house. An outdoor concert is planned for that evening.

The next morning, participants will process a mile north to Bethesda Presbyterian Church for a joint Anglican-Presbyterian religious service honouring the fallen soldiers. That afternoon, people will gather at the battlefield for a secular ceremony and reburial. Organizers have informed Gov. Henry McMaster of the events, and they have reached out to the state’s congressional delegation and to British officials. Horse-drawn caissons already are reserved.

Bostick said he expects some or all of the events to be live-streamed.

The X-rays and strontium isotope analysis likely will shed light on exactly how these men died, their age at the time of death, and the precise circumstances of their death. The DNA analysis will take a bit longer to complete, perhaps returning results during the summer.

The Battle of Camden “is the outstanding symbol of a series of disastrous setbacks suffered by the American side in the South during The War for Independence,” the National Park Service noted on its National Registry of Historic Places nomination form. “These losses, the surrender of Charleston, the wipe-out at Waxhaws, and then Camden, represent the lowest point to which American fortunes sank in that struggle.”

It was a rout that prompted Gates, the commanding officer, to flee along with many of his men, abandoning the now outnumbered Continental regulars to their fate. Their commander, Maj. Gen. Johann de Kalb, was mortally wounded. Congress wanted an inquiry into Gates’ actions, but it never came to pass. Gates was reassigned and Gen. Nathanael Greene assumed command of the Southern forces. It was a consequential change of leadership, a turning point in the war. Over the next two years, Greene and the fighters he commanded succeeded in driving the enemy from the Carolinas and Georgia. On Dec. 14, 1782, the British completed their evacuation of Charleston, boarding ships at Gadsden’s Wharf and sailing off. The war was coming to an end.

Old bone links lost American parrot to ancient Indigenous bird trade

Old bone links lost American parrot to ancient Indigenous bird trade

For centuries, Indigenous communities in the American Southwest imported colourful parrots from Mexico. But according to a study led by The University of Texas at Austin, some parrots may have been captured locally and not brought from afar.  

The research challenges the assumption that all parrot remains found in American Southwest archaeological sites to have their origins in Mexico. It also presents an important reminder: The ecology of the past can be very different from what we see today.     

“When we deal with natural history, we can constrain ourselves by relying on the present too much,” said the study’s author, John Moretti, a doctoral candidate at the UT Jackson School of Geosciences. “These bones can give us kind of a baseline view of the animal life of the ecosystems that surrounded us before huge fundamental changes that continue today began.”  

The study was published in print in the September issue of The Wilson Journal of Ornithology.  

Parrots are not an uncommon find in southwestern archaeological sites dating as far back as the 7th or 8th centuries. Their remains have been found in elaborate graves and buried in trash heaps. But no matter the condition, when archaeologists have discovered parrot bones, they usually assumed the animals were imports, said Moretti.  

Old bone links lost American parrot to ancient Indigenous bird trade
The tarsometatarsus, or ankle bone, of a thick-billed parrot. The bone was collected at an archaeological dig in New Mexico during the 1950s. UT doctoral student John Moretti identified the bone as belonging to a parrot.

There’s a good reason for that. Scarlet macaws — the parrot most commonly found in the archaeological sites — live in rainforests and savannahs, which are not part of the local landscape. And researchers have discovered the remains of ancient parrot breeding facilities in Mexico that point to a thriving parrot trade.   

But there is more to parrots than macaws. In 2018, Moretti found a lone ankle bone belonging to a species known as the thick-billed parrot. It was part of an unsorted bone collection recovered during an archaeological dig in the 1950s in New Mexico.   

A thick-billed parrot.

“There was a lot of deer and rabbit, and then this kind of anomalous parrot bone,” said Moretti, a student in the Jackson School’s Department of Geological Sciences. “Once I realized that nobody had already described this, I really thought there was a story there.” 

Thick-billed parrots are an endangered species and do not live in the United States today due to habitat loss and hunting. But that was not the case even a relatively short time ago. As recently as the 1930s, their range stretched from Arizona and New Mexico to northern Mexico, where they live today. The boisterous, lime-green birds are also very particular about their habitat. They dwell only in mountainous old-growth pine forests, where they nest in tree hollows and dine almost exclusively on pine cones.  

With that in mind, Moretti decided to investigate the connection between pine forests in New Mexico and Arizona and the remains of thick-billed parrots found at archaeological sites. He found that of the 10 total archaeological sites with positively identified thick-billed parrot remains, all contained buildings made of pine timber, with one settlement requiring an estimated 50,000 trees. And for half the sites, suitable pine forests were within 7 miles of the settlement.  

Moretti said that with people entering parrot habitat, it’s plausible to think they captured parrots when gathering timber and brought them home.

“This paper makes the hypothesis that these [parrots] were not trade items,” Moretti said. “They were animals living in this region that were caught and captured and brought home just like squirrels and other animals that lived in these mountains.”  

Moretti relied on thick-billed parrot bones from the United States and Mexico permanently archived in collections at The University of Kansas Biodiversity Institute and the Smithsonian Institution to conclusively identify the lone bone that sparked the research.

Mark Robbins, an evolutionary biologist and the collection manager of the ornithological collections at The University of Kansas, said this study shows the value of natural history collections and the innumerable ways they assist with research.  

“The scientists who originally collected those specimens, they had no idea they would be used in this fashion,” Robbins said. “You can revisit old questions or formulate new questions based on these specimens.”  

The research was funded by the Museum of Texas Tech University, where Moretti earned a master’s degree.   

Revolutionary War Prison Camp Found in Pennsylvania

Researchers say they solved a decades-old riddle this week by finding remnants of the stockade and therefore the site of a prison camp in York, Pennsylvania, that housed British soldiers for nearly two years during the American Revolutionary War.

The location of Camp Security was thought to have been on land acquired by the local government nearly a decade ago. On Monday, an archaeological team working there located what they believe to be the prison camp’s exterior security fence.

The camp housed more than 1,000 English, Scottish and Canadian privates and noncommissioned officers for 22 months during the war, starting with a group of prisoners who arrived in 1781, four years after their surrender at Saratoga, New York. By the next year, there were some 1,200 men at the camp, along with hundreds of women and children.

Researchers say they have solved a decades-old riddle by finding remnants of the stockade and therefore the site of a prison camp in York, that housed British soldiers for nearly two years during the American Revolutionary War.

Fieldwork at the site, which also includes the lower-security Camp Indulgence, has gone on for decades, but the exact spot of Camp Security — where prisoners from the 1781 Battle of Yorktown, Virginia, were kept — had been unknown until a telltale pattern of post holes in a foot-deep trench was uncovered.

“This has been a long project, and to finally see it come to fruition, or at least know you’re not nuts, that’s wonderful,” said Carol Tanzola, who as president of Friends of Camp Security led fundraising for the project.

Lead archaeologist John Crawmer said the location site had been narrowed down after about 28 acres (11 hectares) were ploughed for metal detection and surface collection of artefacts in 2020. That further reduced the search area to about 8 acres (3 hectares), where long exploratory trenches were dug last year.

Those trenches helped the team identify post holes that in turn led to the pattern of holes and a stockade trench that matched stockades at other 18th-century military sites, Crawmer said.

Next spring, Crawmer and other researchers hope to determine the full size of the stockade and perform a focused search for artefacts within and around it.

“Was it circular or square, what’s inside, what’s outside?” Crawmer said. “As we do that, we’re going to start finding those 18th-century artefacts, the trash pits. We’ll be able to start answering questions about where people were sleeping, where they were living, where they were throwing things away, where the privies are.”

Crawmer said there is evidence the vertical posts that formed the security stockade were not in the ground for very long and that they may have been dug up and reused after the camp was closed in 1783.

A contemporaneous account of camp life by a British surgeon’s mate said there was a “camp fever” that might have killed some of the prisoners, and a list of Camp Security inmates was located in the British National Archives. No human remains have been found at the site.

Historians confirmed local lore about the general location of Camp Security and Camp Indulgence after a 1979 archaeological study of a small portion of the property produced buckles, buttons and other items associated with British soldiers of the period. That survey also found 20 coins and 605 straight pins that may have been used by prisoners to make lace.

A camera left in the Yukon by a legendary explorer in 1937 is found 85 years later

A camera left in the Yukon by a legendary explorer in 1937 is found 85 years later

In 1937, legendary mountaineers Bradford Washburn and Robert Bates were exploring Canada’s frigid Yukon region when they had to abandon their gear in order to quickly escape. Nearly 85 years later, the cache of gear they left behind has been found – including Washburn’s camera. 

Professional mountain explorer Griffin Post told CBS News he first heard about the abandoned cache in the book “Escape from Lucania.” Author David Roberts writes about where Washburn and Bates may have left the cache of gear in the Kluane National Park and Reserve.

“But nobody really knew for sure, and that doubt and that possibility that it was still there is what I went on,” Post said. 

Griff Post and the Washburn’s camera, which was embedded in the ice of Walsh Glacier.

Washburn is a mountaineer, explorer, surveyor, mapmaker and author who is also known for the photos he took of the dramatic landscapes he explored. He’s visited many of the world’s wild regions, including remote Alaska and Mount Everest.

Post said Washburn and Bates abandoned their gear because their pilot couldn’t come back to pick them up, so they decided to summit the peak and hike out into Canada. They planned to come back the following winter but never did. 

On a quest to find the cache, Post led a team to the remote Walsh Glacier. Post and Teton Gravity Research — which produces skiing, snowboarding and surfing films — partnered with University of Ottawa Glaciologist Dora Medrzycka, who travelled with them, and mapped out the glacier to determine where the gear could have moved over time. Dr. Luke Copland and a team at the University of Ottawa helped them remotely.

The team found a portion of Washburn’s aerial camera, which is believed to be his first-ever aerial photography camera, according to a press release from Teton Gravity Research. They were also able to retrieve two other cameras with film still loaded inside.

“It was such an emotional rollercoaster because you go in, you’ve done all this research, you’re so excited, and then the first time you fly in you see how vast the terrain is and how much area you’re supposed to cover and how many crevasses the cache could’ve fallen into years ago,” Post said. “It’s like ‘I don’t think there’s any way we can find this.’ It’s so overwhelming.”

However, Post said, searching for the cache ended up feeling fun. 

“At times I felt like a little kid. You’re jumping over a crevasse, like looking for treasure essentially. Like this is wild I get to do this,” he said. “And if we don’t find anything, well as far as adventure goes, we checked that box.”

During a seven-day trip, the crew of seven people searched on foot, ski and snowboard, travelling about 60 miles each, Post said. 

“We found it on the morning of the seventh day,” he added. “It took every minute basically, and in the end, the helicopter was about to take off to come pick us back up, and that was when we found the cache.”

The team found a portion of Washburn’s aerial camera, which is believed to be his first-ever aerial photography camera, according to a press release from Teton Gravity Research. They were also able to retrieve two other cameras with film still loaded inside. 

Archaeologists from Parks Canada, which oversees national parks in the country, returned to the glacier with the team a few weeks later and helped them carefully retrieve what they could, successfully extracting the camera from the ice, according to the press release. 

Post said they will be “examined in the coming weeks and we’re cautiously optimistic something will be salvageable.”

Post said they will be “examined in the coming weeks and we’re cautiously optimistic something will be salvageable.”

The team estimated the camera had moved about 12 miles from where it started, Post said. Until this point, scientists only had data about glacier movement dating back to the 1960s, and analyzing the movement of the cache since 1937 can help them better understand how the velocity and thickness of a glacier may have changed. 

Post said not only was it historically significant to find the cache but “the science was almost cooler.” 

“Because we essentially backfilled three decades of data the science community didn’t have as far as how glaciers moved,” he added.

Lidar Survey Reveals Urban Sprawl of Ancient Maya City

Lidar Survey Reveals Urban Sprawl of Ancient Maya City

A graphic illustrating new details, uncovered using LiDAR laser technology, of the ancient Mayan city of Calakmul, Mexico, in this undated handout image.

Following years of research, Dr. Kathryn Reese-Taylor, PhD, professor in the Department of Anthropology and Archaeology at UCalgary, as well as her team of international colleagues, has used lidar (light detection and ranging) to help uncover more secrets of the enormous ancient Maya city of Calakmul.

As a result, researchers on the Bajo Laberinto Archaeological Project, a University of Calgary-led international and multidisciplinary research project directed by Reese-Taylor, can now better understand the density and landscape modifications of Mexico’s ancient Maya Calakmul settlement.

“By using lidar imagery, we are now able to fully understand the immense size of the Calakmul urban settlement and its substantial landscape modifications, which supported an intensive agricultural system,” says Reese-Taylor.

“All available land was covered with water canals, terraces, walls and dams, no doubt to provide food and water security for Calakmul residents.”

Although the number of people who lived at Calakmul during the height of the Snake King’s rule was not a complete surprise because of previous mapping and archaeological investigations by the Autonomous University of Campeche and INAH, the team was astonished at the scale and degree of urban construction.

Immense apartment-style residential compounds have been identified throughout the surveyed area, some with as many as 60 individual structures, the seats of large households composed of extended families and affiliated members.

These large residential units were clustered around numerous temples, shrines, and possible marketplaces, making Calakmul one of the largest cities in the Americas in 700 AD.

But that’s not all the team was able to see.

“We were also able to see that the magnitude of landscape modification equalled the scale of the urban population,” explains Reese-Taylor. “All available land was covered with water canals, terraces, walls, and dams, no doubt to provide maximum food and water security for the city dwellers.”

What’s next for the team and the technology

Going forward, the lidar survey will be used by INAH to help with policy and planning for the biosphere in anticipation of the expected increased tourism in the area.

The lidar will also continue to support the Bajo Laberinto Archaeological Project, which aims to investigate the causes of the rapid population increase at Calakmul and its effect on the region’s environment.

“We’re excited to see what else this technology will help us learn about Calakmul,” says Reese-Taylor. “It’s such a privilege to be unearthing the secrets of Mexico’s ancient settlements.”

Reese-Taylor and her colleagues on the Bajo Laberinto Archaeological Project will present their preliminary findings from the lidar survey on the INAH TV YouTube channel, on Tuesday, Oct. 25 at 5 p.m. MT. 

Maya Stela Discovered at Uxmal

Maya Stela Discovered at Uxmal

Maya Stela Discovered at Uxmal
The stela was found in Uxmal, a Maya city founded around A.D. 700.

In the archaeological site of Uxmal in the Yucatán peninsula, a Maya stela depicting a god and a goddess has been discovered by a technical team headed by the archaeologist José Huchim Herrera. The monument could represent the duality between life and death.

The director of the National Institute of Anthropology and History INAH, Diego Prieto, announced during AMLO’s Thursday press conference the finding of the Maya stela, which he said “is a commemorative dual stela because it is carved on both sides.”

The north-facing side of the monument features the figure of a goddess with big eyes, a bare chest, and barbels at the corner of the mouth, Prieto said.

The imagery likely represents death, as such depictions were common in the Puuc and Chenes cultural regions in the southern Yucatán peninsula.

The woman depicted is also holding a quetzal bird in her left hand and wears a pectoral decoration with three rows of pearls, bracelets with pearl details and a long skirt.

An INAH graphic highlighting features found on the north-facing side of the stela.

On the south-facing side, Prieto continued, the stela shows the image of a god with a wide-brimmed headdress adorned with feathers and an owl’s head, as well as bracelets, loincloth, and leg bandages.

The man wears a cape and holds a cane in his left hand and a bundle of some kind in his right hand.

The stela was discovered as part of the Program for the Improvement of Archeological Sites (Promeza), which undertakes archaeological projects along the route of the Maya Train.

The director of INAH said that “the importance of the discovery lies in the fact that it was found ‘in situ,’” meaning in the same place the Maya left it: the sunken patio of the ancient city of Uxmal.

Located 62 kilometers south of Mérida, the city of Uxmal is part of the Puuc Route (a collection of five ancient Maya sites in Yucatán) and was founded in A.D. 700.

Uxmal was designated a UNESCO World Heritage Site in 1996.

Remains of an elaborate stone fish trap have been discovered on the seafloor off Southeast Alaska, and scientists say it proves Indigenous people occupied the region 1,000 years earlier than previously believed.

Known as a fish weir, the ancient trap dates back about 11,100 years, the Sealaska Heritage Institute reported in a news release. That makes it likely “the oldest stone fish weir ever found in the world … and it is the first one ever confirmed underwater in North America,” scientists said.

It was discovered over the summer as part of a project funded by NOAA Ocean Exploration to search seafloor caves for evidence of early human occupation, according to the release.

The trap sits about 170 feet below the surface of Shakan Bay, on the west side of Prince of Wales Island, officials told McClatchy News. It takes the shape of five to six “semi-circular structures” that are up to 6 feet wide. Time has worn the walls down to about 1 foot in height, the institute said. 

“Likely the rocks were piled much higher 11,100 years ago. … People would have maintained the weir seasonally by restacking rocks and adding more rocks and possibly wooden stakes,” the institute said.

Such traps were typically built close to shore, in spots that would have been covered at high tide. However, the change in seafloor levels has left the weir “over 2 km (1.2 miles) from the closest modern shoreline.” 

“It further substantiates the great antiquity of Native people in Southeast Alaska,” said anthropologist Rosita Worl of the Sealaska Heritage Institute. “It also demonstrates that Native people had acquired knowledge about salmon behaviour and migrations, then developed the technology to harvest a significant number of salmon.”

Sonar evidence of a structure at the site was first recorded in 2010, but “funding constraints” prevented experts from confirming their theories until this year, the institute said. A robotic underwater craft was used to investigate the structure, piloted by archaeologist Kelly Monteleone at the University of Calgary.

She reports “the entire vessel was bouncing with excitement” when it was confirmed to be a weir in May. “It wasn’t just me that was convinced (in 2010), but the burden of proof was on me,” Menteleone told McClatchy News.

“Other archaeologists and locals were extremely supportive based on the sonar. But, as my dissertation advisor taught me, I had to be sure before it became an archaeological site, i.e. before we were ‘sure’ it was actually there. So for the last 12 years, this location has been a ‘potential’ weir.”

Examples of ancient fish weirs have been found around the world, and often employed the use of pile stones, reeds and/or wooden posts, experts say. They were often built as “low arced walls” across coastal gullies. “During high tide, the fish would swim over the stone walls, and as the tide ebbed, the fish would be trapped behind them, allowing fishers to catch them with nets, spears and other means,” the institute says. Other weirs have been found in Southeast Alaska, but the oldest dated to only around 5,740 years ago, the institute reports.

The age of the weir in Shakan Bay was established “based on sea level reconstruction,” officials said. The world believes it is the work of people who had been in the region long enough to develop sophisticated skills. “It would have taken time for our people to learn enough about the environment and fish behaviour to develop the technology to make the weir and to fish it successfully,” she said in the release.

NOAA Ocean Exploration was a primary financial backer of the project, and it reports the team will return to Southeast Alaska next summer to continue exploring submerged caves and rock shelters using a SUNFISH autonomous underwater vehicle.

Blue Fibers Found in Dental Calculus of Maya Sacrifice Victims

Blue Fibers Found in Dental Calculus of Maya Sacrifice Victims

More than 15 years after its discovery, Belize’s Midnight Terror Cave is still leaving clues about more than 100 people who were sacrificed to the Maya rain god there more than a millennium ago.

Used for burial during the Maya Classic period (A.D. 250 to 925), the cave was named by locals who were called to rescue an injured looter in 2006. A three-year excavation project by California State University, Los Angeles (Cal State LA) professors and students concluded that the more than 10,000 bones uncovered in the cave represented at least 118 people, many of whom had evidence of trauma inflicted on them around the time of death. 

To dive deeper into the victims’ final moments, the latest research didn’t look at bones but instead at their mouths, investigating the calcified plaque from their teeth, known as dental calculus. The study, published Sept. 20 in the  International Journal of Osteoarchaeology(opens in new tab), describes curious blue fibres clinging to the teeth of at least two of the victims.

Study lead author Amy Chan, who’s now an archaeologist working in cultural resource management, started her analysis of the Midnight Terror Cave teeth as a graduate student at Cal State LA, where she was interested in learning more about the dental health of the victims, she told Live Science by email. 

“After finding minimal instances of dental pathology, I became interested in determining what foodstuffs the victims were consuming,” she said.

The blue fiber, likely made of cotton, is from Midnight Terror Cave in Belize.

Dental calculus can preserve microscopic pieces of food that someone ate — such as pollen grains, starches and phytoliths, which are mineralized parts of plants — so Chan scraped the gunk off six teeth and sent it to study co-author Linda Scott Cummings(opens in new tab), president and CEO of the PaleoResearch Institute in Golden, Colorado. Scott Cummings found that the samples contained primarily cotton fibres and that several of those were dyed bright blue.

“The discovery of blue cotton fibres in both samples was a surprise,” Chan said, because “blue is important in Maya ritual.” 

A unique “Maya blue” pigment has been found at other sites in Mesoamerica, where it seems to have been used in ceremonies — particularly to paint the bodies of sacrificial victims, Chan and colleagues wrote in their research paper. These blue fibres were also found in an agave-based alcoholic beverage at burials at Teotihuacan, an archaeological site in what is now Mexico. 

But Chan and her team offered another explanation for the fibres found on the teeth: Perhaps the victims had cotton cloths in their mouths, possibly from the use of gags leading up to their sacrifice. If victims were in custody for extended periods of time, their dental calculus could have incorporated the blue fibres.

“It is interesting that they found coloured fibre in dental calculus,” Gabriel Wrobel(opens in new tab), a bioarchaeologist at Michigan State University who was not involved in the study, told Live Science by email. “Many researchers think that calculus only reflects diet, but this study is a great example of how much more information can be learned.”

Claire Ebert(opens in new tab), an environmental archaeologist at the University of Pittsburgh who was not involved in the study, told Live Science by email that she is “sceptical” that the blue fibres came from gags. However, she noted that dental calculus studies are important because they “can be used to look at other aspects of Maya life, ranging from ritual to domestic.” 

An expanded study including both elite and non-elite people would be worthwhile “to see if the pattern can also be detected” or if “other explanations for the presence of fibers may be more logical,” Ebert said.

Chan and her team agree that their study, while providing the first evidence of blue fibers in the dental calculus of Maya individuals, has some limitations. First, the rate at which plaque forms and hardens varies based on the type of food eaten and a person’s physiology, so the researchers cannot know for certain when the fibers were trapped. Additionally, very few teeth of Midnight Terror Cave victims had dental calculus, to begin with, limiting the team’s analysis. 

“Future studies will provide a more ample context for interpreting this data,” the researchers wrote in their study.
