Description :
This paper presents the results of radiacarbon dating of fossil wood stem remains of larch (Larix decidua) found 1 m below the surface at the base of the front of the Piancabella rock glacier in September 2005 within the framework of geomorphological and geophysical investigations of the Late-glacial and Holocene glacier permafrost evolution in the southern Swiss Alps. The site and the findings are described in their geomorphological context, the findings are examined in relation to the regional late Holocene climatological history and finally, the late Holocene dynamics of the Piancabella rock glacier are discussed.
