• Sommario/riassunto: In combining and revising the two titles 'Past Glacial Environments' and 'Modern Glacial Environments', Dr Menzies and his contributors provide the most comprehensive and wide-ranging book ever prepared on both topics. This text is produced with the student mind, providing accessibility to a complex subject and introducing topics that provide the fundamental underpinnings of knowledge on glaciers, ice sheets, their sediments and landscapes. Modern and Past Glacial Environments features a large collection of photographs, line diagrams and tables and includes examples of glacial environments
