Abstract

The existence of Rocky glaciers in various regions of Chile has been equally recognized by some inventory and not seen by others. Particular studies have revealed its presence in different parts of the country since the mid-20th century. But both these as inventories are far from even expressing real areal extension of distribution as well as characteristics or the volume of water resources that represent. So, the goal of this research is increase the knowledge about the real rock glacier distribution in Chile. In this work we review background information on the existence of Rocky glaciers in the Cordillera of the Andes of Chile, the current knowledge of its zonal and regional distribution. Also, confirms the presence of them in some cases, and its evolution in others since they were described and mapped for the first time. Finally recognize Rocky glaciers not previously identified in the regions of Atacama, Maule, Aysén and Magallanes, which joins other recently reported in the region of Valparaiso. Among them, highlight the Rocky glaciers discovered in the Torres del Paine National Park, between 50° 56’ and 50° 58’ of southern latitude, constituting evidence of the effects of climate change, especially the regional thermal tendency. How results, the existence of different types of rock glaciers and the evolution state of them is stablished in a more wide latitudinal distribution, increasing the actual knowledge and contributing to glacier inventories.
