Geografiska Annaler: Series A, Physical Geography 93, n.o 3 (septiembre de 2011): 151-62. https://doi.org/10.1111/j.1468-0459.2011.00424.x.1468-045910.1111/j.1468-0459.2011.00424.xhttps://hdl.handle.net/20.500.14352/95839Shallow ground temperatures were measured and periglacial and permafrost environments identified at the Chachani volcanic complex in the west-central Andes in southern Peru (16° 11′ S; 71° 31′ W, elevation 6057 m a.s.l.). Three stations were installed at 4850, 4976 and 5331 m a.s.l. on the southern slope and the data were processed to produce ground temperature distribution models at depth and altitude. Snow cover lasts only a few days each year. Air and ground surface temperatures oscillate around 0°C almost daily, but the temperature is stabilized only a few centimetres below the ground surface. The lower limit of thermal conditions for isolated patches of permafrost occurs at 5050 m on the south-facing slopes. Thermal conditions associated with discontinuous permafrost occur from 5250 to 5420 m a.s.l., with continuous permafrost found above this level. The permafrost distribution models show that the rock glaciers observed on the southern slopes of the complex are within the active permafrost zone.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal articlehttps://doi.org/10.1111/j.1468-0459.2011.00424.xopen accessChachani VolcanoGround frost conditionsPermafrostCiencias Sociales54 Geografía
