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 ...
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]
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.
Lake Rogen, Sweden as seen from the north. The forested ridges in the lake are 'Rogen moraines' of which this is the type location. A Rogen moraine, also called ribbed moraine, is a subglacially (i.e. under a glacier or ice sheet) formed type of moraine landform, [1] that mainly occurs in Fennoscandia, [1] Scotland, [2] Ireland [3] and Canada.
The Matterhorn, a classic example of a pyramidal peak.. A pyramidal peak, sometimes called a glacial horn in extreme cases, is an angular, sharply pointed mountain peak which results from the cirque erosion due to multiple glaciers diverging from a central point.
Kames are sometimes compared to drumlins, but their formation is distinctively different. A drumlin is not originally shaped by meltwater, but by the ice itself and has a quite regular shape. It occurs in fine-grained material, such as clay or shale, not in sands and gravels. And drumlins usually have concentric layers of material, as the ice ...
