This article presents investigations of a diverse landscape in the young moraine area of southeastern Schleswig-Holstein (Stormarn county). The northern part of the study area represents a large basin, possibly a glacier basin influenced by glaciofluvial meltwaters or by dead ice. Organic sedimentation occurred in this basin from the Late-glacial (Bölling/Alleröd interstadial complex), followed by a longer lake phase and the growth of a fen after c. 5.000 14C a B.P. The central area of the basin was formed as ice-disintegration landscape – including kames, eskers and esker-like features. Ring-like glaciofluvial landform structures are interpreted as subcircular eskers. Kettle bogs developed in the centres of these landforms from c. 5.000 14C a BP (Atlantic/Subboreal) onwards. The southern and south-eastern part of the study area represents a smoothed moraine zone, that includes a glaciotectonically influenced Saalian core of till, sand and glacilacustrine sediment. Parallel aligned gullies were predominantly formed as tunnel valleys. Some parts of the channels are infilled with glaciolacustrine clays. Several channels, asymmetric in cross-profile, were shaped by periglacial slope denudation.
