WebIt is widely recognized that debris is incorporated mainly at the bed and on the surface of a glacier, and that the transport paths and textural character of glacial sediments are related to the dynamic and thermal characteristics of the glacier. In general terms, polythermal glaciers tend to carry a high basal debris load, and their surfaces ...
