Caratteristiche morfodinamiche di due rock glaciers attivi nel Gruppo Adamello-Presanella
Multitemporal topographic surveys on two rock glaciers in the Adamello-Presanella Group have been carried out. The aim of these surveys was to check the morphometric characteristics of the landforms and to get detailed information about their dynamic behaviour. In order to do this, two rock glaciers...
