Coordinates: 41°30′37″N 87°3′29″W. Valparaiso Moraine at Mink Lake, north of Valparaiso, Indiana. The Valparaiso Moraine is a recessional moraine (a land form 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.
Terminal moraine. 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 ...
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.

Kame delta. A kame delta (or ice-contact delta, morainic delta[1]) is a glacial landform formed by a stream of melt water flowing through or around a glacier and depositing material, known as kame (stratified sequence of sediments) deposits. Upon entering a proglacial lake at the end (terminus) of a glacier, the river/stream deposit these ...
Coordinates: 42°54′11.4″N 83°25′30.6″W. The Hadley Hills are a rugged glacial moraine located in The Thumb of Michigan, that extend from northern Oakland County and into southern Lapeer County . The Hadley Hills surround the village of Hadley; [1] The highest points and most prominent outcroppings are: Pinnacle Point at 1,262 feet ...
A fluted moraine, also called a fluted moraine surface, is a moraine whose surface exhibits numerous glacial flutes. The long axes of these flutes are parallel to the flow direction of the glacier. Fluted moraines are typically associated with terrestrial glaciers, but some have been found in glaciomarine settings. [1] [3] [6]
The Kankakee Torrent was a catastrophic flood that occurred about 19,000 calibrated years ago [1] in the Midwestern United States. It resulted from a breach of moraines forming a large glacial lake fed by the melting of the Late Wisconsin Laurentide Ice Sheet. The point of origin of the flood was Lake Chicago. [1]
The glacier visible at the head of the valley is the last remnant of the formerly much more extensive glacier which carved it. U-shaped valley with lake in Myklebustdalen, Nordfjord, Sogn og Fjordane, Norway. U-shaped valleys, also called trough valleys or glacial troughs, are formed by the process of glaciation.
