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 the front edge of the ice, is driven no further and instead is deposited in an unsorted pile of sediment.
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 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 .
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 ...
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

The Ronkonkoma Moraine, a terminal moraine, predates the Harbor Hill Moraine (which reached Long Island during the Wisconsin Glacial Episode); the Harbor Hill Moraine cut through the Ronkonkoma Moraine's western portions. [2] The Ronkonkoma Moraine and the Harbor Hill Moraine intersect at Lake Success in western Nassau County. [2]
Terminal moraines sweep in a giant arc around the ground moraine zone to the south. These terminal moraines are often incompletely formed and lower than in the Alpine Foreland, but are nevertheless clearly visible in the low-relief of the North German Plain. Because of their many gaps, the neutral term, Eisrandlage ("ice margin location") has ...
