Oldest shoe in Norway, dating to 3,000 years ago, recovered from melting ice patch

The oldest shoe in Norway — a 3,000-year-old bootie from the Bronze Age — is just one of thousands of ancient artifacts that were recovered from the country’s melting mountain ice patches in the past two decades, according to a new report from the Norwegian University of Science and Technology (NTNU).

Unlike objects trapped in acidic soil or beneath gargantuan glaciers, the artifacts recovered from Norwegian ice patches are often found in impeccable condition, showing minimal decomposition and deformation, even after thousands of years of frozen slumber. That’s because ice patches are relatively stable, unmoving and free from corrosive compounds.

Perfectly intact weapons, clothing, textiles, and plant and animal remains have all emerged from the ice, helping to bring thousands of years of Norwegian history to light.

But now, the report authors said, climate change could bring that all to an end.

Within just a few decades, vast swaths of Norway’s ice patches have begun to melt, exposing undiscovered artifacts to the elements and almost certain deterioration, the authors wrote.

“A survey based on satellite images taken in 2020 shows that more than 40 percent of 10 selected ice patches with known finds have melted away,” report co-author Birgitte Skar, an archaeologist and associate professor at the NTNU University Museum, said in a statement. “These figures suggest a significant threat for preserving discoveries from the ice, not to mention the ice as a climate archive.”

The melting past

Ice patches form at high elevations, where snow and ice deposits accumulate and don’t completely melt in the summer. Unlike glaciers, ice patches don’t move, so objects deposited in ice patches can remain stable for hundreds or thousands of years.

When the ice begins to melt, those objects return to the light of day, preserved just as they were when the ice swallowed them up. However, if scientists aren’t able to recover these objects soon after the melting begins, then they run the risk of losing the artifacts to the elements.

Ice patch archaeology has been a tremendous boon to researchers studying the ancient cultures, plants and animals in frosty, elevated regions around the world. In Norway, researchers have uncovered thousands of artifacts belonging to the Bronze Age hunting tribes who hunted reindeer across Northern Europe and southern Scandinavia.

According to the new report, reindeer are drawn to the region’s mountainous ice patches in summer months to seek relief from biting insects and the heat. Where the reindeer went, hunters followed, leaving troves of artifacts behind.

The 3,000-year-old shoe, which was discovered in 2007 in the mountainous region of Jotunheimen in southern Norway, remains a standout find. The small leather shoe would be a size 4 or 5 in today’s U.S. sizes, suggesting it belonged either to a woman or a youth.

The shoe was discovered alongside several arrows and a wooden spade, suggesting the site was an important hunting ground. Dated to approximately 1100 B.C., the shoe is not only the oldest shoe in Norway, but possibly the oldest article of clothing discovered in Scandinavia, according to the researchers who discovered it.

Further surveys of the Jotunheimen site revealed even older artifacts, including a 6,100-year-old arrow shaft — the single oldest object discovered in a Norwegian ice patch, according to the researchers. Its presence near the shoe, suggests that the site was continuously used by humans over many millennia.

Despite these remarkable finds, the report authors worry that countless other cultural artifacts could disappear before they are recovered, thanks to the effects of climate change. A 2022 report from the Norwegian Water Resources and Energy Directorate estimates that 140 square miles (364 square kilometers) of ice patches — an area roughly half the size of New York City — have melted since 2006. If artifacts are not recovered from these patches soon after they are exposed, they risk being lost, damaged or destroyed forever.

Few ice patches in Norway have been systematically surveyed, especially in northern Norway, which remains mostly unstudied. To mitigate this, the researchers suggest launching a national ice patch monitoring program, using remote sensors to systematically survey ice patches and secure any objects that emerge from the melt.

“We used to think of the ice as desolate and lifeless and therefore not very important. That’s changing now, but it’s urgent,” report co-author Jørgen Rosvold, a biologist and assistant research director at the Norwegian Institute for Nature Research, said in the statement. “Large amounts of unique material are melting out and disappearing forever.”

Reconstruction Shows Teen Who Died in Norway 8,300 Years Ago

About 8,300 years ago, a teenage boy with an unusual skull and short stature may have scampered along the rocky coast of what is now Norway, pausing to regain his balance as he clutched a fishing rod. Now, a new full-body reconstruction of the Stone Age teenager — nicknamed Vistegutten, Norwegian for “the boy from Viste” — is on display at the Hå Gamle Prestegard museum in southern Norway.

The boy’s reconstruction was a months-long project, but researchers have known about Vistegutten since 1907, when archaeologists found his remains in a Mesolithic, or Middle Stone Age, cave in Randaberg, along Norway’s western coast. 

A few things stand out about the 15-year-old boy: At 4 feet, 1 inch (1.25 meters) tall, he was short for his age, even by Mesolithic standards; a condition known as scaphocephaly meant that his skull had fused too early, forcing his head to grow backward instead of sideways; and he may have died alone, as his remains were found as if he had been leaning against a cave wall. 

“Either he was placed like this after his death, or he actually died in this position,” Oscar Nilsson, a forensic artist based in Sweden who created the boy’s likeness, told Live Science in an email. “This can give the impression of a lonely boy, waiting in vain for his friends and family to show up … but we know nothing about how he died.”

Scaphocephaly occurs when the sagittal suture on the top of the skull fuses too early, giving the skull a ridged appearance. But “it is not associated with any developmental problems or intellectual disabilities,” Sean Dexter Denham, an osteologist at the Museum of Archaeology at the University of Stavanger in Norway who helped analyze the skeleton, told Live Science in an email. And while the boy’s unusual skull and short stature may have given him a unique appearance, his remains suggest he was well-fed and healthy. 

“The sheer volume of animal remains found at the site also attests to a plentiful food supply,” Denham said. The cave, which is about 30 feet (9 m) deep and 16 feet (5 m) wide, is filled with kitchen waste; ornaments, such as decorated bone pendants; and fishing tools, including hooks, harpoons and barbed bone points, suggesting that ancient “people lived, worked, cooked and slept at the Viste site,” Nilsson said. 

“The fishing hook that the reconstruction of the boy from Viste holds in his hand is a replica of one of these findings,” Nilsson noted. 

To make the reconstruction, two computed tomography (CT) scans were taken of the skull, allowing Nilsson to create a 3D-printed plastic replica. Because he wasn’t sure about the boy’s facial tissue thickness, Nilsson relied on measurements of modern Northern European 15-year-old boys. “Of course, we don’t know how transferable these measurements are to someone who lived 8,000 years ago,” Nilsson said. “But it’s the best we can guess.”

He noticed that the forehead was “quite childish in appearance, rounded and projecting from the face a bit. This is most probably coming from the scaphocephaly,” Nilsson said, adding that the teenager also had a thin nasal ridge but a nose that was “rather broad at the lower parts.” 

An analysis of the boy’s DNA showed that his skin tone, hair, and eye color “likely would be close to the other ‘Norwegian’ findings from the period,” including mostly brown eyes, dark hair, and intermediate skin tone, Nilsson added. 

He intended to give the teenager a subtle smile, “but as I got deeper into the project, I could not get rid of a feeling of a lonely boy,” Nilsson said. “I imagine him on his way to the sea (which at his time was extremely near the cave) to catch some fish. It is very windy in this part of Norway, so I worked quite a lot to make it look as if the wind blows in his hair and clothes.”

Stone Age wardrobe

The boy’s clothes are made by Helena Gjaerum, a Sweden-based independent archaeologist who uses prehistoric techniques for tanning leather. “Oscar wanted a summer outfit and that the boy would be barefoot, standing on the beach,” Gjaerum told Live Science in an email. “Therefore, a tunic was decided from the beginning.”

She made the tunic from de-haired and fat-tanned elk skin, and put two bark-tanned salmon skins around his waist. A bag that hangs off his belt was sewn from deerskin. All of these animals’ remains were found at the archaeological site. To add to the authenticity, “The suit is sewn with both sinew thread and leather straps,” Gjaerum explained. “It is smeared with ash and grease to look believable.”

The boy’s necklace was crafted from salmon vertebrae and a broken seashell. His remains are “one of the oldest skeletons ever found in Norway,” Kristine Orestad Sørgaard, an archaeologist at the Museum of Archaeology at the University of Stavanger who helped Nilsson understand the archaeological context, told Live Science in an email. “It’s a great reminder that people in the past were very much like us, despite living in a world very different from our own.”
