Abstract

A rock glacier system is studied in an Andean high valley of the semi-arid region of Chile, basin of the Límari River, in order to recognize the different constituent forms, their dynamics, and the relationships with the surroudings and with the different evolutive stadia. The studied landforms are both glacial and periglacial. Their features include some of the evolutionary phases of rock glaciers. The landforms correspond to a tongue shape inactive rock glacier and to active talus rock glaciers. They can be simple, wavy or lobated. The importance of slope periglacial processes is established in relation with the present dynamic of these rock glacier features. Rock glacier morphogenetic conditions are directly linked to original processes, but also to periglacial mechanisms in their evolution, giving account of a complex system in wich a geomorphological continuum is demostrated. The changes in the level of activity of the system is due to a clear seasonality associated to a brief and cool winter and a large and temperate summer, characteristic of the Andes high mountains of the semi-arid Chilean region.
