The prehistoric mariners rowed their canoe into a secluded channel and then onto the island's sandy beach, just above the high-tide mark. One person got out of the boat and stood for a moment, facing northwest. Others, including another barefoot adult and child, followed the leader and walked toward higher, drier land.

Today, roughly 13,000 years later, their footprints have been preserved in a layer of sediment and confirmed to date from the last ice age. The discovery, on Calvert Island on the central coast of British Columbia, Canada, adds to the growing body of evidence that suggests ancient humans crossed from Asia to North America and traveled south along the Pacific shoreline.

"This finding provides evidence of the seafaring people who inhabited this area during the tail end of the last major ice age," said University of Victoria anthropologist Duncan McLaren, lead author of the new study in the journal PLOS One, in a statement.

Most anthropologists believe that early peoples migrated from Asia to North America across Beringia, the region where Russia's Chukchi Peninsula and Alaska face each other across the Bering Strait. Then the migrants took two possible routes. One popular theory, proposed in the 1930s, suggests people traveled south along an ice-free corridor that lay on the eastern slope of the Rocky Mountains where two colossal ice sheets split from one other. A more recent theory proposes that they sailed along a coastal route from Alaska to Washington State.

The coastal route lies within the territories of the Heiltsuk First Nation and Wuikinuxv First Nation. Their oral histories describe how the scattered islands between the open ocean and the edge of the ice sheet remained unglaciated. On these refuges, their ancestors subsisted on the abundant fish, shellfish, and marine mammals and likely used watercraft to travel between the islands. "Heiltsuk oral history talks about our people living in our territory before the ice age, and talks about the physical features of the landscape that our people witnessed change over time due to the ice, which influenced things like place names in our territory," William Housty, chair of the Heiltsuk Integrated Resource Management Department board of directors, tells Mental Floss.

Archaeological evidence affirming the histories is scarce, in part because few researchers have focused on the area. In 2014, McLaren and colleagues from the University of Victoria and the Hakai Institute, along with representatives of the First Nations, began combing the beach at a Calvert Island site called EjTa-4 for sediments dating back to the late Pleistocene epoch (also known as the Ice Age, which ended 11,700 years ago). Back then, the sea level around Calvert Island was 6.5 to 10 feet lower than it is today, so the team concentrated on the intertidal zone. After probing several test holes, they found what appeared to be footprints near the base of a huge shell midden.

Over the next three field seasons, they continued to excavate a 6.5-foot-by-13-foot pit, removing strata of sand, pebbles, and organic matter before striking the layer of clay. "The site was below the high-tide water line, so we only had one day from the time we opened the last layer. When the high tide came up it would wash everything away," Jennifer Walkus, the research liaison between the Wuikinuxv Nation and Hakai Institute, tells Mental Floss. "We had an idea from the test pit the previous year that there might be footprints, so we knew that day was going to be busy. It was amazing as the last layer was pulled up and the measurements were taken."

In the substrate, the team found 29 individual human tracks, darkened by time, left by at least three different people—two adults and a child—based on the dimensions of the individual prints. "The fact that they were footprints was more and more obvious as the measurements came in and there were three lengths," Wallkus says. The orientation of some of the tracks at the ancient shoreline indicated that a group of people may have disembarked from a watercraft and walked northwest, toward higher ground, with their backs to the prevailing wind.

Researchers also collected samples of clay and fragments of shore pine from the sand underneath the prints. Radiocarbon dating confirmed that the pine bits, and the footprints, were between 13,317 and 12,633 years old.

"I can't speak for the Nation as a whole, but for me, it's a validation of the fact that we have been here for much longer than the previous narrative," Walkus says. "The fact that these footprints put people in the vicinity in the time of glacial recession underlines that our legends are grounded in living in our area over huge spans of time."

When William Housty, who was not present at the dig, heard of the discovery, "I immediately started to think about our first ancestors and the stories of their origin," he says. "I also thought that, once again, science [and] archeology have confirmed what our oral history has been telling us all along."

13-Year-Old Amateur Archaeologist Discovers the Buried Treasure of a Danish King

In January, amateur archaeologist René Schön and his 13-year-old student Luca Malaschnitschenko were scouring a field on an island in the Baltic Sea when something small and silver triggered their metal detector. What they initially thought was aluminum trash turned out to be a coin from a 10th-century treasure hoard that once belonged to a Danish king, AP reports.

Schön and Malaschnitschenko discovered the site on the eastern German island of Ruegen, but it wasn't until mid-April that state archaeologists uncovered the hoard in its entirety. Both of the amateur archaeologists were invited back to take part in the final dig, which spanned 4300 square feet.

The treasure trove includes pearls, jewelry, a Thor's hammer, and about 100 silver coins, with the oldest dating back to 714 CE and the most recent to 983 CE. Experts believe the collection once belonged to the Viking-born Danish king Harald "Harry" Bluetooth, who abandoned his Norse faith and brought Christianity to Denmark.

Threatened by a rebellion led by his son, the king fled Denmark in the late 980s—around the same time the silver hoard was buried—and took refuge in Pomerania, on the southern coast of the Baltic Sea. He died there in 987.

Harry Bluetooth derived his nickname from his bluish dead tooth. Today his legacy lives on in the Swedish Bluetooth technology that bears his name. The symbol for the tech also uses the runic characters for his initials: HB.

According to the archaeologists who worked there, the dig site represents the largest trove of Bluetooth coins ever discovered in the southern Baltic region.

This May Be the Oldest Tattoo Kit in the World

Tattooing is an ancient art, but it has left only ephemeral traces in the archaeological record. Examples of mummies with ink-decorated skin do exist—such as Ötzi the Iceman and the Siberian Ice Maiden—but they're rare. And archaeologists are only just beginning to distinguish tattoo needles from other tools that were used for tasks like working leather or weaving baskets.

Despite those challenges, a pair of researchers thinks they've identified what could be the world's oldest tattooing toolkit: a set of pointy, ink-stained needles that were carved out of wild turkey bones and then buried in a Native American grave at least 3600 years ago.

The burial was found west of Nashville, Tennessee, at a riverside campsite called the Fernvale site, which had been used by prehistoric hunter-gatherers for centuries. The settlement was excavated to make way for a bridge in 1985, but archaeologists at the time did not fully analyze the findings. The set of bone needles, pigment-filled half-shells, and stone tools were collectively labeled a toolkit and put into storage, where they spent the next three decades.

"It was one of these situations where it went into a collection and nothing was done with it," says Aaron Deter-Wolf, an archaeologist with the Tennessee Division of Archaeology and an expert in ancient tattoos.

Deter-Wolf teamed up with Tanya Peres, a zooarchaeologist at Florida State University, to take a fresh look at the set of artifacts. They were initially interested in the toolkit because it resembled a medicine bundle—a collection of artifacts that was bound together to act like a portable shrine in more recent Native American cultures. But after examining the objects, the researchers thought they might be dealing with a tattoo kit.

"By the arrival of the Europeans, virtually every Native American group in the Great Plains and the Eastern Woodlands practiced tattooing," Deter-Wolf tells Mental Floss. "If it's something that widespread and that important, we suspect that it is very deeply rooted in Native American history."

Their theory got a boost from another study published last year, in which Christian Gates St-Pierre, an archaeologist at the University of Montreal, tattooed pig skin with bone tools to test the wear-and-tear patterns that prehistoric tattoo needles should exhibit. He found that when it was used for tattooing, a bone needle would develop a bright polish—but only on the first 3 millimeters of the tip.

Deter-Wolf recently took those experiments one step further. He re-created one of Ötzi's tattoos on his own skin, using a bone tool and black ink to make 1500 individual punctures on his left wrist—and a permanent tattoo.

Deter-Wolf and Peres said that two of the needles in the kit had the same wear-and-tear signatures that Gates found in his experiments. "At this point there's not another activity that we know of that would create that same pattern on bone tools," Deter-Wolf says.

They also found traces of red and black pigment on the tips of the tools. (They're awaiting the final results of an analysis to figure out the chemical makeup of this paint.) They presented their preliminary findings this week at the annual meeting of the Society for American Archaeology in Washington, D.C.

The toolkit is thought to be at least 3600 years old and could be even more ancient: Initial results from a radiocarbon study of shells found at the same site suggest an age of 5200 years. Either way, the tools predate a group of 3000-year-old tattooing tools made from volcanic glass that were identified in 2016 at an archaeological site on an island in the South Pacific.

While scholars know a lot about more recent Native American tattooing practices because of historical accounts and ethnographic studies after European contact, prehistoric tattooing remains more mysterious. For now it's impossible to know what kind of tattoos the Fernvale tools would have been used to create, or what meaning tattooing had for the people who lived along this Tennessee river valley during this era, called the Archaic period in North America.

"I think there has to be a whole lot more work done on Archaic lifeways in general before we can even start to parse the deeper meaning of tattooing in this period," Peres says. "We're still arguing about what they were eating and what kind of houses they living in, which are more durable things in the archaeological record."

Deter-Wolf expects archaeologists will identify more tattoo kits hiding in collections: "What I suspect is that once we start looking at more of these things, we're going to find that tattooing is an incredibly widespread activity."
