National audienceOne of the specificities of the Vercors mountains (Northern french Alps) is that every inner late-glacial settlement with preserved faunal remains they include are specialised in alpin Marmot (Marmota marmota L.) exploitation: l’Olette (950 m a.s. l.), Les Pierres (1040 m a. s. l.) , Colomb (1050 m a. s. l.), la Passagère (1050 m a. s. l.), Bobache (700 m a. s. l.) and les Freydières (820 m a. s. l.). That activity was uncovered at the beginning of the XXth century by Hippolyte Müller and it has been confirmed by numerous field and faunal works since. However it appears that the lack of thickness of the late glacial sedimentary records at high altitude produced a palimseste of diachronical cultural settlements for most of t...
