Abstract

We present air and ground thermal temperature data of some places located between 750 and 885 m.a.s.l. around two rock glaciers in the Cerro Krund cirque (Tierra del Fuego, Argentina) at altitudes between 750 and 885 m during the years 2009 and 2010. The data obtained, together with geomorphological observations and the dynamics observed between 2004 and 2010 show that the highest is an active rock glacier, which confirms the presence of permafrost for this sector of the Sierra de Alvear above 850 meters. Bellow this altitude, in the lower rock glacier, we could not found any permafrost evidences.
