The two processes of advancement and retreat have the power to transform a landscape and leave behind a series of landforms that give great insight into past glacial presence and behavior. Landforms that result from these processes include moraines, kames, kettles, eskers, drumlins, plains, and proglacial lakes.
[1] [3] Examples include glacial moraines, eskers, and kames. Drumlins and ribbed moraines are also landforms left behind by retreating glaciers. Many depositional landforms result from sediment deposited or reshaped by meltwater and are referred to as fluvioglacial landforms. Fluvioglacial deposits differ from glacial till in that they were ...
A drumlin, from the Irish word droimnín ("little ridge"), first recorded in 1833, in the classical sense is an elongated hill in the shape of an inverted spoon or half-buried egg [1] [2] formed by glacial ice acting on underlying unconsolidated till or ground moraine. Assemblages of drumlins are referred to as fields or swarms; [3] [4] they ...
Eskers form near the terminal zone of glaciers, where the ice is not moving as fast and is relatively thin. [5] Esker in Sims Corner Eskers and Kames National Natural Landmark, Washington, US. (Trees at the edge of the esker and the single lane road crossing the esker to the right of the photo provide scale.)
Kames are not normally located in proximity to one another, however in Edmonton, Alberta, numerous kames are found nearby, forming the Prosser Archaeological Site. The Fonthill Kame in southern Ontario is in a densely populated area. Examples can also be found in Wisconsin and at the Sims Corner Eskers and Kames National Natural Landscape in ...
The Glacial Kame culture was a culture of Archaic people in North America that occupied southern Ontario, Michigan, Ohio, and Indiana from around 8000 BC to 1000 BC. The name of this culture derives from its members' practice of burying their dead atop glacier-deposited gravel hills .
Kame deltas form in association with other glacial features such as kettles and eskers. [3] Kettle lakes can form in between kame deltas. Eskers are remnants of old stream sediment flows that are exposed after the glacier has melted. These formations give indication that kame deltas formed during times of glaciation.
The inclusion of the moraine illustrates how land-based rocks and sediment are carried by ice. Erratics provide an important tool in characterizing the directions of glacier flows, which are routinely reconstructed used on a combination of moraines, eskers, drumlins, meltwater channels and similar data. Erratic distributions and glacial till ...
