Geology. of drumlins has been much discussed, but there is,as yet, no generally accepted conclusion, and the subject is stillunder active inquiry.

In seismic science, a discontinuity is a surface (such as the boundary between rock units) where seismic waves abruptly change velocity. erosion by glaciers In glacial landform: Rock drumlins A feature similar to roches moutonnées, rock drumlins are bedrock knobs or hills completely streamlined, usually with steep stoss sides and gently sloping lee sides. Both roches moutonnées and rock drumlins range in length from several metres to several kilometres and in height… drumlins indicates they were formed by a flow towards the northwest. This is an enigma in the glacial theory, as former ice sheets must have spread from their centers where ice thickness was greatest. No force is Drumlins occur in areas where the ice advanced over previously formed till plains.

The glacial geology of Minnesota is rather young relative to the bedrock Streamlined hills of till aligned parallel to ice flow direction are called drumlins.

The rolling foothills found in this same area follow the same slip-fold formation as the Rockies, and therefore are formed on the north-south axis. The Chautauqua Drumlin Field encompasses an area of roughly 2,500 sq. km and spans from northwestern Pennsylvania into southwestern New York State, where more than 750 drumlins have been identified (Saha, 2010).

Drumlins occur in areas where the ice advanced over previously formed till plains. They are elongate in the direction of ice movement and most of them have a front or "stoss" slope at the head end which is somewhat steeper than the lee slope.

Low 1994-06-01 ‘Here, a drumlin, an oval mound smooth-sculpted by glaciers, rises to give an uninterrupted panorama of sea, fields and forests from its grassy crown.’ More example sentences ‘About 10,000 years ago, boulders and soils trapped beneath retreating ice sheets were moulded into drumlins, and it is believed there is an island for each day of the year.’ Facies modelling of the internal structure of drumlins has resulted in recognition of five major facies associations within the Irish drumlin belt. The facies associations are linked with a sequence of depositional events during the last deglacial phase (ca. 20-16 ka BP). Drumlin sediments were formed by basal till deposition, subglacial fluvial-lacustrine sedimentation, sheet flow, debris ‘Here, a drumlin, an oval mound smooth-sculpted by glaciers, rises to give an uninterrupted panorama of sea, fields and forests from its grassy crown.’ More example sentences ‘About 10,000 years ago, boulders and soils trapped beneath retreating ice sheets were moulded into drumlins, and it is believed there is an island for each day of the year.’ 2008-06-07 2015-06-16 Drumlins around Horicon Marsh, Wisconsin, in an area with one of the highest concentration of drumlins in the world.The curved path of the Laurentide Ice Sheet is evident in the orientation of the various mounds.

The name is derived from the Gaelic word druim (“rounded hill,” or “mound”) and first appeared in 1833. Drumlins are generally found in broad lowland regions, A drumlin, from the Irish word droimnín, first recorded in 1833, in the classical sense is an elongated hill in the shape of an inverted spoon or half-buried egg formed by glacial ice acting on underlying unconsolidated till or ground moraine.
