Some researchers deem drumlin formation as occurring close to ice margins and believe fields are built up incrementally as the margin retreats, whereas others believe that extensive patterns of drumlins may have formed approximately synchronously under wide swathes of an ice sheet. Drumlins: Erosional Landforms. Drumlins are smooth oval shaped ridge-like features composed mainly of glacial till with some masses of gravel and sand. The long axes of drumlins are parallel to the direction of ice movement.

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

The greater part of Glasgow is built on a succession of smooth whale-backed hills composed of boulder clay, geologically termed drumlins. Evidence of this hilly nature of the city is afforded by the names of many districts; for example Hillhead, Gilmorehill, Garnethill, Govanhill and Mount Florida, to mention but a few.
