A subglacial till intrusion in meltwater sediments is described from a locality in southern Denmark. The structure is interpreted as a large till wedge, developed during glacier flow from the southeast. The intrusion seems to have occurred at a time when the glaciofluvial sediments were unfrozen. The possibility of development of till wedges in frozen sediments is discussed.
