High altitude karstic environments often preserve permanent ice deposits within caves, representing a lesser-known portion of the cryosphere. Despite being not so widespread and easily reachable as mountain glaciers and ice caps, ice-caves preserve a great deal of information about past environmental changes and paleoclimatic evolution. Since one of their main characteristics is to have ground-ice ...[Read More]
