A hill of compact, unstratified, glacial drift or till, usually elongate or oval, with the larger axis parallel to the former local glacial motion.
A low, rounded, elongate hill or ridge of compact till left by a glacier.
A streamlined, spoon shaped hill created by glacial deposition. The steep side of a drumlin faces in the direction from which the glacier came. The process that forms drift drumlins is still debated by glaciologists. The most popular explanation is that the pressure of the ice overriding existing moraines, drift, and till is sufficient to deform them and mold them into elongate ridges. They are steeper on the upslope side because that is where the greatest pressure is exerted by the flowing ice.
A mound left by glaciation composed of till. It is usually shaped like an oval cut in half with the long part parallel to the direction in which the ice flowed.
A low, smoothly rounded, elongate hill. Drumlins are deposits of compacted till that are sculpted beneath the ice of a flowing glacier. The long axis of a drumlin parallels the flow direction of the ice.
Gaelic "ridge"] A hill formed from glacial debris.
A long, spoon-shaped hill that develops when pressure from an overriding glacier reshapes a moraine. Drumlins range in height from 5 to 50 meters and in length from 400 to 2000 meters. They slope down in the direction of the ice flow.
stretched out hill made of glacial till in the direction of glacial movement.
an elongated hill or ridge of glacial drift
a low, smoothly rounded hill of compact glacial till, built under the margin of the ice and shaped by its flow.
a mound of glacial drift
an elongate or oval hill of glacial drift formed during the last ice age
a smoothly rounded, elongated and oval hill, mound or ridge of compact glacial till
a streamlined, elongate hill composed of glacial drift
An elongated ridge of glacial sediment sculpted by ice moving over the bed of a glacier. Generally, the down-glacier end is oval or rounded and the up-glacier end tapers. The shape is often compared to an inverted, blunt-ended canoe. Although not common in Alaska, drumlins cover parts of the Eastern and Midwestern United States (Irish). ---------------------- Erratic A rock of unspecified shape and size, transported a significant distance from its origin by a glacier or iceberg and deposited by melting of the ice. Erratics range from pebble-size to larger than a house and usually are of a different composition that the bedrock or sediment on which they are deposited.
Streamlined, oval-shaped hill formed by glacial activity and usually comprising unsorted sediment, or till
An elongated, teardrop-shaped hill. These streamlined hills were sculpted in the direction of glacial ice movement. They often occur in groups, known as swarms. Because drumlins generally form miles behind (or "up-ice" from) an end moraine, they are rare along the Ice Age Trail. The Farmington Drumlins, in Waupaca County, is the largest swarm of drumlins along existing segments of the Ice Age Trail. State highway 60, between Columbus and Hartford, and interstate highway 94 between Madison and Sussex, cross one of the largest drumlin swarms in the world.
a streamlined, elongated egg-shaped hillock of glacial drift formed under a moving glacier during the ice age. The long axis of the hillock is aligned parallel to the direction of the ice flow. Drumlins usually occur in swarms or fields.
A smooth, streamlined, cigar shaped hill formed beneath moving glacial ice.
A smooth, glacially streamlined hill that is elongate in the direction of ice movement. Drumlins are generally composed of till.
A small hill, composed of glacial drift with hog back outline, oval plan, and long atlas oriented in the direction of ice movement. Drumlins usually occur in groups, forming what is known as basket of eggs topography.
A streamlined, elongate hill formed when a glacier overrides glacial till.
an elongated hill formed by glacial till material deposited in the direction of the glacier that formed it.
n. Elongated mound of glacial sediment deposited parallel to ice flow.
An oval or elongated hill of glacial drift. The long axis of the hill shows the direction of glacial movement. The blunt end of the drumlin points "upstream" (toward the origination of glacial movement), and the more tapered end of the drumlin points "downstream." Drumlins probably migrated across the landscape with, but more slowly than, the glaciers which created them.
elongated, streamlined hill molded by glacial deposition or erosion. Usually found in fields containing hundreds of individualdrumlins, located behind major end moraines and parallel to ice flow direction.
small oval shaped hills with the long axis lying parallel to the direction of the flow of ice. These small hills are composed of boulder clay.
a glacial feature; specifically small, oval, asymmetric hills from 100 to 2000m long, formed inside end moraines; drumlin landscapes are especially common in Down.
streamlined, elongate hill, usually composed of till, shaped by advancing glacial ice.
A smooth, streamlined hill composed of till and, in many cases, bedrock.
A drumlin (Irish droimnÃn, a little hill ridge) is an elongated whale-shaped hill formed by glacial action. Its long axis is parallel with the movement of the ice, with the blunter end facing into the glacial movement. Drumlins may be more than 150 ft (45 m) high and more than Â½ miles (0.8 km) long, and are often in drumlin fields of similarly shaped, sized and oriented hills.
