Switzerland’s melting glaciers are revealing ancient secrets, according to an article published on October 2, 2026, by SWI swissinfo.ch.

Glacier archaeologist Marcel Cornelissen describes glaciers as “treasure troves”. As they melt, artifacts emerge on the surface (rather than being deeply buried), giving unique insights into the past. Finds are increasing with accelerated ice loss. Researchers are often alerted by mountaineers who spot objects, then document, stabilize, and transport them for laboratory analysis and dating.

Notable discoveries

• Bronze Age weapons (including a bow and arrowheads from the Lötschen Pass on the Bern-Valais border)
• Ancient animal remains (such as a cow’s skull)
• A small Roman statue
• A rosary
• Other items linked to Mesolithic rock crystal extraction and use

Some of these appear in an exhibition at the Glacier Garden in Lucerne. Cornelissen is involved in the “Bergeis” project at the Uri Institute Cultures of the Alps and is especially interested in reconstructing daily life from thousands of years ago (e.g., hunting, protecting livestock, or possible conflicts).

The urgency

Glacial ice acts as a major archaeological archive that is disappearing rapidly.

Related reporting notes that about a fifth of Swiss Alpine ice has vanished in five years, with 2026 heatwaves and low winter snowfall accelerating the loss of dozens of glaciers.

Cornelissen warns that “a great deal of archaeological knowledge is being lost”, as future analytical methods may arrive too late for much of the remaining ice.

The piece is a short (~3- minute) feature translated from German, focusing on the race to document these finds before they are gone.

“Bergeis” (Mountain Ice) is a research and public archaeology project at the Uri Institute Cultures of the Alps (Urner Institut Kulturen der Alpen and Institut Kulturen der Alpen), an affiliated institute of the University of Lucerne based in Altdorf, Canton Uri, Switzerland.

Focus and goals

It investigates the extraction, processing, and use of rock crystal (Bergkristall and quartz) by Mesolithic hunter- gatherer societies in the Swiss Alps (primarily Cantons Uri and Valais), roughly 8000/7000- 5800 BC. The project examines how people sourced and worked this material at high altitudes, its societal value, and the broader environmental and climatic context (including past and present glacier dynamics).

A key site is a rock- crystal extraction fissure near the Untere Stremlücke and Fuorcla da Strem Sut (around 2817- 2831 m), exposed by the retreating Brunnifirn glacier (Oberalpstock area).

Discovered in 2013 by a crystal hunter (“Strahler”), it yielded:

• Rock- crystal tools, manufacturing waste, and knapping debris
• Rare organic remains preserved in the ice (antler artefacts and wood fragments, the oldest ice-preserved organic finds known in the Alps at the time)

This is described as the first securely dated Mesolithic glacial rock-crystal extraction site in the Swiss Alps. The project also studies related assemblages elsewhere in Uri and Valais and includes further field surveys (in collaboration with cantonal archaeological services).

Dual aims:

• Scientific research into alpine Mesolithic life, raw- material procurement, and the deep history of crystal hunting (“Strahlen”), a tradition that continues in the region.
• Public outreach: raising awareness of alpine cultural history, potential glacier/ice-patch finds, and encouraging hikers, mountaineers, crystal hunters, and locals to report discoveries to authorities.

Leadership and timeline

• Project lead: Marcel Cornelissen, M.A. (freelance archaeologist and Junior Research Fellow at the institute, specializing in early post-glacial and alpine archaeology). He runs it on a mandate basis.
• Official run: approximately January 2021- October 2023 (with related fieldwork, analysis, and outreach continuing; listed as 2021- 24 in some of Cornelissen’s records).

Related activities and outputs

• Excavations and surveys (e.g., 2020 work at the Stremlücke site).
• Exhibitions such as “Bergeis- Strahlen der Steinzeit” (shown at Talmuseum Ursern in Andermatt and Stockalperschloss in Brig, 2022- 2023/2025), featuring tiny rock- crystal tools, large- format photos by Valentin Luthiger, and documentation of the fieldwork team.
• Publications (including a 2022 paper in Norwegian Archaeological Review on the glacially preserved site) and outreach materials such as flyers and brochures

The project sits under the institute’s research focus on “Forms of cultural inscription” and highlights how melting glaciers both reveal and threaten this archaeological archive. It connects prehistoric alpine practices with contemporary mountain culture and climate change.
