The medial moraine is the double line of debris running down the centre-line of the glacier. Lateral moraines can rise up to 140 meters (460 ft) over the valley floor, can be up to 3 kilometers (1.9 mi) long, and are steeper close to the glacier margin (up to 80 degrees) than further away (where slopes are typically 29 to 36 degrees).

There is a glacier-fed lake in addition to the formation of a small channel heading in the southeast direction. During glacial retreat, meltwater flows in the opposite direction of the retreat, causing braided streams and channels to form. A terminal moraine creates a barrier helping to trap water in a newly-formed glacial lake.
Moraine: Built up mound of glacial till along a spot on the glacier. Feature can be terminal (at the end of a glacier, showing how far the glacier extended), lateral (along the sides of a glacier), or medial (formed by the merger of lateral moraines from contributory glaciers). Types: Pulju, Rogen, Sevetti, terminal, Veiki
Throughout the area concerned, the various glacial pulsations that have produced impressive moraine accumulations over time are clearly evident. Of particular note among these is the left lateral moraine of the ancient glacier, known as the Serra di Ivrea: this is the largest formation of its kind existing in Europe. [3]
This process left depressions ranging from small ponds to large lakes and enclosed valleys. Water-filled kettles range in depth from 3 to 200 ft (0.9 to 60 m). The topography of this area is widely varied between the lakes and kettles and the hills of glacial deposits, which can rise up to 300 ft (90 m) from the lakes. The largest include Holy ...
PPhysiography of the Valparaiso Moraine. Valparaiso Moraine at Mink Lake, north of Valparaiso, Indiana. The Valparaiso Moraine is a recessional moraine (a landform left by receding glaciers) that forms an immense U around the southern Lake Michigan basin in North America. It is a band of hilly terrain composed of glacial till and sand.
The Tinley Moraine would be an earlier recession of the Michigan Lobe a short ways north, returning southward, with both wind and water driven drifts, mixed with the return of the ice front for a short duration before the northward retreat of the ice front, establishing the Lake Chicago sequence of shorelines and moraine features in northern ...
