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.

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
1.3 Moraines of the Maritimes of Canada and NE United States. 1.4 Moraines of Western Canada. ... This a partial list of glacial moraines.
Lateral Moraine: moraine in upper Engadin left by retreating glacier Lateral moraines are ridges of sediment deposited alongside the glacier running parallel to the long axis of the glacier. These sediments are typically deposited on top of the ice ( supraglacial till) at the margin of the glacier and as such do not experience the same amount ...
A lateral moraine that is no longer being actively added to with glacial material because the glacier has retreated for climatic reasons, is known as a flank moraine. In the Alps the remaining flank moraines were usually formed during the Little Ice Age in medieval times.
Lateral moraine on a glacier joining the Gorner Glacier, Zermatt, Swiss Alps. The moraine is the high bank of debris in the top left hand quarter of the image. Glaciologist Erin Pettit in Antarctica, 2016. Glaciology (from Latin glacies 'frost, ice' and Ancient Greek λόγος 'subject matter'; lit.
Lateral moraines are formed on the sides of the glacier. Medial moraines are formed when two different glaciers merge and the lateral moraines of each coalesce to form a moraine in the middle of the combined glacier. Less apparent are ground moraines, also called glacial drift, which often blankets the surface
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]
