The Calderone Glacier is situated on Como Grande, Gran Sasso d’Italia. It is the only glacier in the Apennine mountain chain and is now rapidly reducing and thinning. Geophysical surveys were conducted there in 1992 for the purposes of measuring the ice thickness and determining the bedrock morphology. Six cross and one longitudinal radio-echo sounding (R.E.S.) profiles were carried out on the lower sector of the glacier. G.S.S. radar equipment, including an 80-Mhz antenna, was used. The glacier showed ice thickness of 26 m at most, with evident over-deepening. The debris cover showed a maximum thickness of 2 m.
