Melting ice in Norway’s highest mountains is exposing artefacts up to 6,000 years old

Forty-eight prehistoric arrows were recovered from melting ice in the Norwegian mountains during this season’s fieldwork, and the oldest of them dates to between 5,000 and 6,000 years ago. The work was carried out by archaeologists of the Secrets of the Ice programme, which was reported on October 6, 2026.

The arrows come with clothing, tools, everyday objects and even children’s toys, all of it released by ice that has held it since the Stone Age. Until recently, most artefacts emerging from melting Norwegian ice dated to the Viking Age or the two millennia before it, so a haul reaching back to the Neolithic is an unusual shift in the record.

Jotunheimen ice patches

HeritageDaily’s report says only that the finds came from Norway’s highest mountains, at an altitude of around 2,000 metres. A second report published the same day by the Indian Defence Review is more specific: the work focused on the Kvitingskjølen area of the Jotunheimen mountains in Innlandet County, at the Langfonne, Storefonne and Hanklefonne sites, where the programme spent three weeks this field season.

Jotunheimen is the range that holds Norway’s tallest peaks, which squares with the description. The programme itself works there under a long-running arrangement; its own history pages trace the first exploratory surveys in the Jotunheimen ice at Juvfonne and Lauvhøe in 2007, led by Elling Utvik Wammer and Lars Pilø, and a systematic survey of Juvfonne in 2009. The Glacier Archaeology Program is, as The Weather Network described it in 2020, a cooperation between Innlandet County Council and the University of Oslo’s Museum of Cultural History.

The oldest arrow, and why reindeer hunters left it

The arrow dated to 5,000 to 6,000 years ago includes a slate arrowhead, part of a wooden shaft and traces of binding material, according to the Indian Defence Review. The same report says the programme’s oldest objects overall are more than 6,000 years old, so the 6,000-year figure belongs to this season’s find and is not a ceiling for the programme. Earlier work at Langfonne, summarised by Life in Norway, put the oldest of 68 arrow shafts there at around 4100 BC.

The explanation offered for where the arrows turn up is reindeer. According to HeritageDaily, in warm summers the animals moved onto snow and ice patches to escape insects and cool down, and Stone Age hunters placed themselves where the herds gathered. An arrow that missed could sink into snow and later become part of the ice. Old artefacts therefore do not mean the sites were ice-free in the Stone Age; HeritageDaily’s account is that people used patches of ice that stayed largely undisturbed for millennia, which is also why the objects survived in such condition.

A race against the thaw

The urgency comes from preservation. Wood, leather, bone, textiles and feathers can survive for thousands of years while permanently frozen, but they deteriorate soon after exposure. Julian Robert Post-Melbye, an archaeologist at the University of Oslo, told HeritageDaily that at an altitude of 2,000 metres the team has only days, maybe weeks, to secure the finds once they are exposed.

At some sites he has studied over the past 15 years, about half the ice has already disappeared. Researchers estimate that many ice patches holding archaeological material could vanish completely within two decades, a timescale the Indian Defence Review echoes in its statement that most ice-preserved sites in Innlandet County could disappear entirely within 20 years.

The recovery pattern follows a clear sequence. Ice melts back in late summer, objects that had been locked in place slide or wash onto bare ground, and the field team has to reach them before sun, wind and meltwater do. That timetable explains why the programme works in short, intense seasons of a few weeks at altitude, and why the three sites named in the Indian Defence Review were each visited within the same three-week window.

The programme’s own scale gives the loss some measure. The Indian Defence Review reports a record of 73 sites and more than 5,000 artefacts recovered over almost 20 years, with the 48 arrows of this season forming part of that total.

An Ötzi-like find as a long shot

Post-Melbye told HeritageDaily that the team hopes for something comparable to Ötzi, the roughly 5,000-year-old natural mummy found in the Ötztal Alps in 1991, and that such a discovery is possible. The conditions are demanding. A person would have to die on the ice, go unrecovered and unscavenged by animals such as wolves or wolverines, and be covered quickly by snow and ice.

The numbers that carry the story are specific: 48 arrows this season, one of them 5,000 to 6,000 years old, and an estimate that the ice holding such objects may be gone within about twenty years.
