A drumlin is a long narrow ridge of gravel and rock deposited by a moving glacier, one end of which is blunt and the other end tapering. The tapered end of the elongated hill is pointed, with the blunt end facing towards the direction of glacial advance. A drumlin is composed of many layers which are thought to have been added repeatedly to a central core over period of time. Glacial till, along with rock, makes up these layers, and is composed of unsorted glacial sediment. There are many different classifications of till, i.e primary, secondary, lodgement, deformation, melt-out and sublimation tills, but some scientists have proposed that there be only one classification; deformation till. This proposal is due to the difficulties of an accurate classification of the till in relation to its environment.
Drumlins are an evident landmark, in some instances 150 feet high by half of a mile long, and are typically present in Canada, Ireland, Minnesota, New York and Wisconsin. Cousins of the drumlin include crags and eskers.
