[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 ...
The soil of Seattle, the state's largest city, is approximately 80% glacial drift, most of which is Vashon glacial deposits , [7] and nearly all of the city's major named hills are characterized as drumlins (Beacon Hill, First Hill, Capitol Hill, Queen Anne Hill) or drift uplands (Magnolia, West Seattle).
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.
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 ridge crests of eskers are not usually level for very long, and are generally knobby. Eskers may be broad-crested or sharp-crested with steep sides. [5] They can reach hundreds of kilometers in length and are generally 20–30 m (66–98 ft) in height. The path of an esker is governed by its water pressure in relation to the overlying ice.

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.
