This is a geomorphological study about a south slope valley in the Catalonian Central Pyrenees, characterized by a Quaternary morphogenic action. The glacial and periglacial
dynamics have been studied drawing a conclusion from the shapes of the relief and their origin. This has allowed to make a basic geomorphological cartography. Now it is already possible to begin more detailed works on diverse phenomena, glacial and periglacial, which were produced or which are being produced in these places
