With the disappearance of the Corral de la Veleta glacier in the Sierra Nevada in 1913, Il Calderone became one of Europe's southernmost known glaciers (42°28′N, 13°33′E), being slightly to the north only compared to Snezhnika (latitude of 41°46′09″ N) and Banski Suhodol Glaciers in Pirin Mountain in Bulgaria. If present deglaciation trends continue, the Calderone may soon share Corral de la Veleta's fate. The discovery of a number of small glaciers in the Prokletije in 2009 seemed to threaten Calderone's positions.
