Drumlins The Forming of A Landscape By Matthew O’Hare Theories and experiments as presented in The Origin of Glacially Fluted Surfaces - Observations and Theories By G.S. Bolton and Drumlin Formation Time: Evidence from Northern and Central Sweden By Ĥưattestrand et al.

What are Drumlins The word drumlin comes form the Irish word druim. Drumlins are made up of sediment deposited by a glacier. Swarms of drumlins have shaped the geography of many areas around the world.

Form of Drumlins

Introduction to The Origin of Glacially Fluted Surfaces Disputes existing theories of tunnels causing drumlins Proposes new theory involving pressure differences caused by obstructions Flutes similar to shear marks

Method and Research of Boulton 13 glaciers Height of obstruction important Subglacial observations Till-fabric measurements Folding

Theory Cavities will tend to occur when: Flute sizes depend on the stresses surrounding it. Rejects frozen till hypothesis The Formation of Individual Flutes

Interrelationship Between Flutes on Fluted Surfaces Claims ideas are erroneous of rhythmic mechanism to spacing of flutes. Depends on number of boulders in glacier Flutes interact to form different shapes

Conclusions of Boulton
