Drumlins are typically between 250 and 1,000 m (820 and 3,280 ft) long and between 120 and 300 m (390 and 980 ft) wide. [8] Drumlins generally have a length to width ratio of between 1.7 and 4.1 [8] and it has been suggested that this ratio can indicate the velocity of the glacier. That is, since ice flows in laminar flow, the resistance to ...

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.
A "drumline," also known as the "battery," or "batterie," is a section of percussion instruments usually played as part of a musical marching ensemble.A drumline can also be a section on their own competing against other drumlines.
Drumlins may be composed of stratified or unstratified till ranging in size from sand to boulders. The non-uniformity of drumlin composition is representative of the diverse origin of the sediments. [38] Banding or layering of till may occur in drumlins as till accumulates on the drumlin formation in successive layers. [38]
Drumlin – an elongated whale-shaped hill formed by glacial action. Butte – an isolated hill with steep sides and a small flat top, formed by weathering . Kuppe – a rounded hill or low mountain, typical of Central Europe .
Drumlins are found in groups called drumlin fields or drumlin camps. One of these fields is found east of Rochester, New York; it is estimated to contain about 10,000 drumlins. Although the process that forms drumlins is not fully understood, their shape implies that they are products of the plastic deformation zone of ancient glaciers.
Clew Bay (/ ˈ k l uː /; Irish: Cuan Mó) is a large ocean bay on the Atlantic coast of County Mayo, Ireland.It is roughly rectangular and has more than a hundred small islands on its landward side; Ireland's best example of sunken drumlins.
