Moraines can be classified either by origin, location with respect to a glacier or former glacier, or by shape. [13] The first approach is suitable for moraines associated with contemporary glaciers—but more difficult to apply to old moraines, which are defined by their particular morphology, since their origin is debated. Some moraine types ...
Terminal moraines are one of the most prominent types of moraines in the Arctic. One notable terminal moraine is Trollgarden in Norway , once thought to be magically constructed by trolls . In North America, the Outer Lands is a name given to the terminal moraine archipelago of the northeastern region of the United States ( Cape Cod , Martha's ...
The Lake Erie basin has two moraines of the same age as the Valparaiso Moraine, the Mississinewa Moraine and the Union Moraine. These moraines formed from the Lake Erie Lobe of the continental glacier. In Michigan the Kalamazoo Moraine is of the same time period. It is the result of the Saginaw lobe of the Laurentian glacier.

The size of the deposited sediments which form a moraine can range from clay to boulder sized. Moraines can be reworked by further glacial action or meltwater into other fluvioglacial landforms. [21] Both original and reworked moraines record a continuum of processes occurring on the landscape as a result of glacial presence.

Drift is often subdivided into unstratified (unsorted) drift (glacial till) that forms moraines and stratified drift (glaciolacustrine and fluvioglacial sediments) that accumulates as stratified and sorted sediments in the form of outwash plains, eskers, kames, varves, and so forth. The term drift clay is a synonym for boulder clay. Both are ...
The Oak Ridges Moraine. The Oak Ridges Moraine is an ecologically important geological landform in the Mixedwood Plains of south-central Ontario, Canada.The moraine covers a geographic area of 1,900 square kilometres (730 sq mi) between Caledon and Rice Lake, near Peterborough.
There is little difference between the soils mixture of the Tinley Moraine and the Valparaiso Moraine. There is a greater quantity of silt and clay similar to a fine grained lake sediments. [1]
