Drumlin

A drumlin is a smooth, elongated hill formed by glacial activity, typically composed of compacted till or bedrock. They have a streamlined shape, usually pointing in the direction the glacier moved, and are often found in groups called drumlin fields. These landforms indicate the direction of past ice movement and provide clues about glacial history. Drumlins can range from a few meters to several kilometers long and are important for understanding landscape development and glacial processes. Their shape results from the reshaping and deposition of sediments as glaciers advance and retreat over time.
