Abstract

Air and ground temperatures were measured at 5 sites from 4137 m to 5020 m asl on the southwest slope of the volcano between 2001 and 2007. Snow lies on the ground for only a few days each year and has almost no effect on periglacial process distribution. Daily freeze-thaw cycles at the ground surface are numerous at the summit (around 212 days annually), but cycles cease only a few centimetres below the surface, so that frost action does not occur below 60 cm depth. Permafrost is present at 4900 m asl on north-facing slopes with a 60 cm thick active layer
