Gran Sasso

22 July 2023

On Gran Sasso occurs the only Apennine glacier, the Calderone, at 2.775 metres located at the foot of Corno Grande; it is the southernmost glacier in Europe. Plains and valleys alternate between the peaks, such as Campo Imperatore, Val Mavone, Vallone d’Angora and Fosso Chiarino. Monti della Laga, compared to other Apennine mountains, has the characteristic of being mostly made of tertiary sandstone, a sedimentary rock less pearmeable than limestone, which led to the development of a complex surface water system, with many streams and waterfalls.
