Terminal moraine of Wordie Glacier, Greenland Map of the Salpausselkä terminal moraines in Southern Finland. A terminal moraine, also called an end moraine, is a type of moraine that forms at the terminal (edge) of a glacier, marking its maximum advance. At this point, debris that has accumulated by plucking and abrasion, has been pushed by ...
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
When the glacier melts, this unconsolidated debris forms ridges. The shape of a terminal represents the shape of the glacier snout or terminus. [26] Terminal moraine refers to the moraine occurring at the point of the furthest advance of a glacier. A recessional moraine is a ridge of deposited debris that occurs when the glacier is stationary ...
End moraine size and shape are determined by whether the glacier is advancing, receding or at equilibrium. The longer the terminus of the glacier stays in one place, the more debris accumulate in the moraine. There are two types of end moraines: terminal and recessional. Terminal moraines mark the maximum advance of the glacier.
The dam can consist of glacier ice or a terminal moraine. Failure can happen due to erosion, a buildup of water pressure, an avalanche of rock or heavy snow, an earthquake or cryoseism, volcanic eruptions under the ice, or massive displacement of water in a glacial lake when a large portion of an adjacent glacier collapses into it.
The Marseilles moraine is a terminal moraine that encircles the southern tip of Lake Michigan in North America. It begins near Elgin, Illinois , and extends south and west of Chicago metropolitan area , turning eastward 30 miles (48 km) to 40 miles (64 km) south of the lake in Kankakee and Iroqouis counties, entering Indiana .
a gravel field or sandur outwash plain in front of the terminal moraine chain a glacial meltwater valley , the Urstromtal , through which meltwaters from the glacier flowed away. The term "glacial series" is restricted to landforms created by glaciers and classified by geomorphological rules, as opposed to the glacial sediments and sedimentary ...
The "Outer Lands" coloured in green. The Outer Lands is the prominent terminal moraine archipelagic region off the southern coast of New England in the United States. This eight-county region of Massachusetts, Rhode Island, and New York comprises the peninsula of Cape Cod and the islands of Nantucket, Martha's Vineyard, the Elizabeth Islands, Block Island, and Long Island, as well as ...
