Nature and origin of ground ice, Sandhills Moraine, southwest Banks Island, Western Canadian Arctic
Abstract The Sandhills Moraine is a Late Wisconsinan lateral moraine complex on southwest Banks Island. The occurrence of ice‐ablation landforms, ground ice slumps, kettle lakes and catastrophic lake drainage in winter suggests the presence of substantial bodies of massive ground ice. The distinctiv...
