The oldest existing cadastre  – Porro (1925) compiled the first “List of Italian Glaciers” (Parma, Ufficio Idrografico del Po, 61 p.) And immediately after Porro and Labus (1927) created the first “Atlas of Italian Glaciers” ( Florence, IGM) with the systematic census of Italian glaciers, among the most ancient glaciological land registers. 774 glaciers were recorded, represented in 4 tables at the scale of 1: 500,000. The list included 773 alpine glaciers and 1 Apennine glacier, the Calderone Glacier, in the Gran Sasso massif, among the southernmost glaciers in Europe.
