Supraglacial lake — A supraglacial lake is any pond of liquid water on the top of a glacier. Although these pools are wict|ephemeral, they may reach kilometers in diameter and be several meters deep. They may last for months or even decades at a time, but can empty… … Wikipedia
supraglacial till — Till deposited on top of or within the upper part of a glacier or ice sheet. Melting of glacial ice deposits supraglacial till atop subjacent material, which forms topographic highs on a resultant landscape. Supraglacial till types include… … Glossary of landform and geologic terms
Ice sheet dynamics — describe the motion within large bodies of ice, such those currently on Greenland and Antarctica. Ice motion is dominated by the movement of glaciers, whose gravity driven activity is controlled by two main variable factors: the temperature and… … Wikipedia

melt-out till — A till that may be either subglacial or supraglacial in origin. Melt out till forms by slow melting of debris rich stagnant ice, but without secondary flow processes. The fabric and clast orientations, imparted by ice processes, remain mostly… … Glossary of landform and geologic terms
Till — is unsorted glacial sediment. Glacial drift is a general term for the coarsely graded and extremely heterogeneous sediments of glacial origin. Glacial till is that part of glacial drift which was deposited directly by the glacier. It may vary… … Wikipedia
Esker — An esker is a long winding ridge of stratified sand and gravel, examples of which occur in glaciated and formerly glaciated regions of Europe and North America. Eskers are frequently several kilometres long and, because of their peculiar uniform… … Wikipedia
Ablation zone — On a glacier, the ablation zone, zone of ablation or zone of wastage is the area in which annual loss of snow through melting, evaporation, iceberg calving and sublimation exceeds annual gain of snow and ice on the surface. Of these, melting is… … Wikipedia
