Talk "Rock crystal and glaciers - rays in the Stone Age"

Finds from the Maderanertal valley in Uri prove that people had already been looking for crystals around 10,000 years ago - i.e. shortly after the last ice age and long before people even practised agriculture or built pile dwellings in the area that is now Switzerland. The artefacts discovered in 2013 in a crystal fissure near the Untere Stremlücke at 2800 metres above sea level, at the transition from the Maderanertal to the Surselva, are thus the oldest traces of human existence in the canton of Uri.

Archaeologist Marcel Cornelissen will present the findings of the research project "Mountain ice. Rock crystal from the Alps in the Mesolithic period" on Saturday, February 22, 2025, in Curaglia near Disentis/Mustér.
