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.
The Namibian drumlins are a geologic feature in Namibia. Since drumlins only occur as the result of glaciers, researchers determined they are the relic of an ice age in the late Paleozoic Era. [1] The researchers measured the supposed rock drumlins with satellite imagery available on the Internet.
The Withrow Moraine and Jameson Lake Drumlin Field is a National Park Service–designated privately owned National Natural Landmark located in Douglas County, Washington state, United States. [1] Withrow Moraine is the only Ice Age terminal moraine on the Waterville Plateau section of the Columbia Plateau.
Glacial meltwater causes further erosion and the characteristically unusual shape of these landforms that distinguishes them from drumlins. Sediment grains located in a kame can range from fine to course-grained and cobble size to boulder-sized [ 28 ] Others describe the size range as from sands to gravels. [ 29 ]
The drumlins and depressions alternating in Raigastvere. Vooremaa ("Drumlin Land" in Estonian; also Saadjärv Drumlin Field [citation needed]) is a 977 km 2 (377 sq mi) landscape region mostly in Jõgeva County, Estonia. It consists of drumlins and depressions that were formed by glacial accumulation and erosion. All the landscape elements such ...
Till plains are also the location in which drumlins, drumlin fields, flutes, and additional moraines form, all composed of glacial till. [4] The material composition of till plains vary greatly, and is dependent on the travel path of the transporting glacier, indicated by the provenance of the deposited material.
Fjord – Long, narrow inlet with steep sides or cliffs, created by glacial activity; Geo – Inlet, a gully or a narrow and deep cleft in the face of a cliff; Gulf – Large inlet from the ocean into the landmass List of gulfs; Headland – Landform extending into a body of water, often with significant height and drop
Glacial landforms are landforms created by the action of glaciers. Most of today's glacial landforms were created by the movement of large ice sheets during the Quaternary glaciations . Some areas, like Fennoscandia and the southern Andes , have extensive occurrences of glacial landforms; other areas, such as the Sahara , display rare and very ...
