Ground moraines are disorganised piles of rocks of various shapes, sizes and of differing rock types. 2. End moraines are ridgelike accumulations of drift built along any part of the margin of an active glacier. They have also been referred to as end moraine where the hummocks occur in a distinct band, and ground moraine … A terminal, or end, moraine consists of a ridgelike accumulation of glacial debris pushed forward by the leading glacial snout and dumped at the outermost edge of any given ice advance. Bennett, Ground moraines are moraines that form in rolling hills or irregular planes that are left as a glacier retreats. Although seldom more than 5 metres (15 feet) thick, it may attain a thickness of 20 m. GROUND MORAINES Rolling-to-flat landscapes that form under the ice sheet are referred to as ground moraine, or till plain.
