Drumlins

Drumlins are a type of glacial landform that are often found in regions that were covered by ice sheets during the last ice age. They are elongated, tear-shaped mounds of glacial till that are typically aligned in the direction of the ice flow.

Formation of Drumlins

Drumlins are formed through the process of glaciation. As a glacier moves over the landscape, it picks up rocks, sediment, and other materials, which are then deposited as the glacier retreats. These deposits form the characteristic shape of drumlins, with a blunt end facing the direction from which the glacier advanced, and a tapered end pointing in the direction of the ice flow.

Characteristics of Drumlins

• Elonagted, tear-shaped mounds
• Composed of glacial till
• Aligned in the direction of ice flow
• Blunt end faces the direction of glacier advance
• Tapered end points in the direction of ice flow
