Description :
This article contains preliminary results of the field studies on the altitudinal alteration of geomorphological features and processes as a reflection of the Quaternary events. The huge stabilized landslides are the main feature of the slope morphology. They were produced in a periglacial zone of the older Rio Blanco glaciation. The present glacial and cryonival systems were affected by the Punrun glaciation phase and postglacial climatic conditions. The valley bottoms and lowermost parts of the slopes were transformed by mass movements and mud/debris flows in the postglacial period.
