Abstract

Remnants of a Pleistocene landslide have been observed during field investigations of Quaternary alluvial formations of the Isle River at Petit-Bost. Abundant frost features have also been found in the colluvium suggesting that sliding may be closely linked with Pleistocene periglacial conditions. With regard to the debate on permafrost distribution in France during the Pleistocene, this study gives support to a wide extent of permafrost at least to the latitude 45°N southward, during the coldest periods. It also points out that frost-induced slope instability may have played a major, but still underestimated role in many French regions north to this latitude
