文摘

•: Drumlin relief at Múlajökull reflects basal till deposition and erosion.
•: Surges deposit and shear till layers across the glacier forefield.
•: Till between drumlins is more consolidated than till within drumlins.
•: High effective stresses between drumlins cause erosion there during quiescent flow.
•: Patterns of till consolidation contradict leading models of drumlin formation.
