GeologyGlaciology

Quick Answer

A drumlin is a streamlined hill made of glacial sediment. Its shape records the direction that ice once moved across the land.

The Full Story

Drumlins are found in clusters called drumlin fields and are associated with past ice sheets. They are usually elongated, with a blunt end facing the direction from which the ice came and a tapered tail pointing down-ice. Their exact origin is still studied, but they clearly reflect glacial shaping. Drumlin landscapes are common in parts of Ireland, Canada, and the northern United States.
