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 517 3 $aModern & past glacial environments 606 $aGlaciers 606 $aGlacial epoch 615 0$aGlaciers. 615 0$aGlacial epoch. 676 $a551.31 701 $aMenzies$b John$01505067 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910784330603321 996 $aModern and past glacial environments$93734478 997 $aUNINA
