Abstract
A small mummified marmot, returned by the ice melting, was found by chance by a mountain guide in August 2022 in the Aosta Valley Alps, at Gressoney-La-Trinité, on the east face of the Lyskamm (Monte Rosa group) at 4.300 meters altitude. The Efisio Noussan regional Museum of Natural sciences promoted the recovery of the find, its conservation and the first analyzes in collaboration with the Institute for Mummy Studies, Eurac Research (Bolzano, Italy). Radiocarbon dating has attested that the specimen lived around 6,600 years ago. Computerized tomographic (CT) examen allowed to investigate the state of conservation of both the soft tissues and the skeleton of the animal and to estimate the sex and the age at the time of death. For the find of undoubted historical-cultural value, a study for the museum display was therefore initiated through a scientific-multidisciplinary working group. The adaptation of the pre-existing museum exhibition itinerary, at the Saint-Pierre Castle (Aosta), therefore envisaged the creation of a patented showcase with modified atmosphere for the marmot conservation, a communication campaign, and the naming.
