The Origin of Penitents
Abstract Penitents are observed on all the snow fields and glaciers of the Santiago Andes between 4000 and 5200 m. They are caused by the prolonged action of the sun in a dry and cold atmosphere, The sublimation of the snow or ice allows the crests to maintain their temperature below 0° C., while in...
