The Mesolithic Berglibalm Rock Shelter (Muotathal, Ct. Schwyz / CH)

Abstract

The Berglibalm rock shelter is located in the municipality of Muotathal in the Bisistal valley at an altitude of 1140 m a. s. l. The areas excavated in 2015 and 2019 measured 5 m2 and yielded the remains of an Early Mesolithic layer dating from around 8766 to 7596 BC. The charcoal concentrations recorded showed that hazel and maple were the main species used for firewood. The excavation also unearthed many well-preserved faunal remains, a small quantity of plant macrofossils and a lithic assemblage comprising 535 artefacts including 15 microliths. The raw material analysis revealed that the hunter-gatherers preferred local and regional raw materials including fine-grained quartzite (»Ölquarzit«). Some long-distance imports attested to contacts to the Chur and Vorarlberg regions in the east, the Ticino in the south and the Upper Rhine Valley or southern Black Forest region in the north. The rock shelter served as a campsite for Mesolithic hunters targeting ibex, chamois, deer and wild boar deep in the Bisistal valley.
