With the disappearance of the Corral de la Veleta glacier (37° N) in 1913, which lay in Spain's Sierra Nevada, "Il Calderone" became Europe's southernmost known glacier (42°28′N, 13°33′E) until the discovery of a number of small glaciers in the Prokletije in 2009. If present deglaciation trends continue, the Calderone will soon share Corral de la Veleta's fate.
In 1794, the Calderone had an estimated volume of over 4 million cubic meters; by 1916, the glacier’s volume had decreased to 3.3 million cubic meters, and by 1990, it had decreased to 360,931 cubic meters. it:Ghiacciaio del Calderone In 1998 Italian glaciologists at a symposium in L'Aquila predicted that the Calderone would vanish within a few decades.
