48 ancient arrows just melted out of the ice in Norway’s Jotunheimen mountains

Archaeologists working in Norway’s Jotunheimen mountains have pulled 48 prehistoric arrows from three melting ice patches this year, several of them still fitted with wooden shafts and sinew bindings, and one topped with a slate arrowhead radiocarbon-linked to roughly 5,000 years ago. The recoveries close out the 20th field season of a glacial archaeology program run by Innlandet County, which has now logged more than 5,000 artifacts since it began in 2006. Rising summer temperatures are exposing older ice than the program has reached before, and with it, older weapons.

Espen Finstad, who edits the program’s field reports, credited the haul to three intensive weeks of fieldwork in September, timed to beat the first snow. His team worked three neighboring ice patches on the Kvitingskjølen plateau: Langfonne, Storfonne and Handklefonne.

Forty-eight arrows across three melting ice patches

Langfonne alone has given up 68 arrows since record-keeping began there, more than any other ice site anywhere in the world, according to a report HeritageDaily published on the season’s finds. The site has produced that volume of weapons while shrinking to less than 30 percent of the size it held twenty years ago, a retreat fast enough that researchers now expect each new season to reach ice that has not been exposed to open air since the objects first froze into it.

Storfonne and Handklefonne, the two patches surveyed alongside Langfonne this year, do not carry that same multi-decade recovery record, but they contributed enough material in three weeks to push the season’s total past prior years. Finstad’s program treats the three sites as one reindeer-hunting landscape rather than separate find spots, since hunters appear to have worked all three for the same purpose across thousands of years.

A 5,000-year-old arrowhead with its shaft still attached

The single most striking object was that slate arrowhead, recovered still gripping two fragments of its original wooden shaft, with traces of the birch bark tar once used to bind the head in place. Program staff recovered and documented 48 prehistoric arrows from melting mountain ice in Jotunheimen this year, a range that runs from that Stone Age point through shafts dating roughly 2,000 years later, well into the Bronze Age.

Lars Pilø, an Innlandet archaeologist who has worked in glacier archaeology for more than a decade, has described the terrain that produces these finds as unlike any lowland dig, where soil, roots and centuries of plowing tend to scramble whatever is buried. “This site differs so enormously from other archaeological sites in the lowlands,” Pilø said of ground where people have lost arrows and other objects for more than 6,000 years, with the oldest dated to roughly 6,100 years ago and the newest to the 13th century. Reindeer climbing to the snow each summer to escape warble flies gave hunters a predictable target across that entire span, and it is generations of missed shots, arrows that struck snow instead of an animal and were never recovered, that built the site’s unmatched arrow count.

Two decades of data behind Innlandet’s ice patrol

Since the program’s watershed first season in 2006, its surveys across Innlandet have recorded 73 archaeological sites and recovered more than 5,000 artifacts, spanning wood, leather, textile and worked stone that would have rotted away anywhere the ice had not sealed them. This year’s finds fit a pattern the program has tracked for several seasons: the objects surfacing now skew older than the ones surfacing a decade ago, because the ice retreating today has not been exposed since before it froze.

That shift means the newest finds are not always the most recent artifacts by age. A shaft lost 300 years ago can sit closer to the surface than one lost 3,000 years ago, so a single season now regularly mixes Bronze Age points with Stone Age ones, a pattern glacial archaeologists elsewhere in Scandinavia have started tracking as a rough gauge of how deep a given patch has thawed.

From the ice to a refrigerated case within days

Stationary ice patches preserve organic material far better than moving glaciers, which grind and scatter whatever they carry; by contrast, isolated, non-moving ice fields are excellent contexts for the preservation of artifacts until the moment meltwater finally frees them. That difference is why Jotunheimen’s find sites still yield birch bark tar and sinew rather than bare stone points, and why archaeologists return to the same three ice patches year after year instead of treating each melt as a one-time event.

New arrivals from the ice go into a refrigerated display case at the Norwegian Mountain Centre in the nearby town of Lom, often within days of being pulled from the mountainside, so visitors can see a 5,000-year-old arrowhead before conservators move it into long-term storage. Whether next year’s melt reaches older ice still, or simply repeats this year’s count, is for now a question the mountain will answer before the archaeologists do.
