Description :
The formation of a moraine mound (hummocky moraine) complex at the Neoglacial limit of Pedersenbreen, Svalbard is discussed. Observations of the debris structure within Pedersenbreen are used to explain the formation of the moraine mound complex. A model for the formation of such moraine mounds by englacial thrusting either as part of a glacier surge or due to flow compression at a polythermal ice margin is developed.
