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).

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]
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
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 ...
The Straing Moraines circled in red. The Strand Moraines is an ancient lateral moraine of the Koettlitz Glacier, deposited at the outer edge of Bowers Piedmont Glacier on the west shore of McMurdo Sound, in Victoria Land. The morraine is 20,000 to 5,000 years old and has an ice core formed by both glacier ice and saltwater ice. [1]
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.
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.
Blue Glacier is a large glacier located to the north of Mount Olympus in the Olympic Mountains of Washington. [4] The glacier covers an area of 1.7 sq mi (4.4 km 2 ) and contains 580,000,000 cu ft (16,000,000 m 3 ) of ice and snow in spite of its low terminus elevation. [ 2 ]
