Glaciation of the region of the Caviahue-Copahue caldera (Neuquén province): A reinterpretation

The previous suggestion of their being two glaciations (« first» and «second») in the Caviahue-Copahue region and neighbouring areas is modified. New studies led to the interpretation of a single glacial episode. Deposits in Hualcupén and Pillun-Challa valleys, related to a rock-avalanche and a huge...

description The previous suggestion of their being two glaciations (« first» and «second») in the Caviahue-Copahue region and neighbouring areas is modified. New studies led to the interpretation of a single glacial episode. Deposits in Hualcupén and Pillun-Challa valleys, related to a rock-avalanche and a huge slide respectively, were confused as terminal moraines of a «second» glaciation. The hummocky surface of those accumulations and their morphological similarity to moraine landscape, probably are the main reason for the misunderstanding.
