In the lower and middle Werra valley a terrace is located 5—8 m above the valley plain. It attains a considerable width in several places, its structure and overburden (sometimes loess) indicate a High Wuermian lower terrace. Probably during the Late Glacial it was dissected by 0.5—1.0 m deep channels, which were subsequently infilled by probably redeposited lower-terrace gravel or finer-grained sediment. Owing to temporarily accessible exposures near Eschwege, the Late Glacial and Early Holocene fluvial history may be reconstructed more satisfactorily here than in the GDR section of the Werra, which Ellenberg investigated thoroughly (1967—1975). "Ried" (peat bog) deposits in former Werra channels may be pre-Alleröd and early Tundra to Boreal in age. Like the Leine valley, the Werra valley contains two "Auelehme" (meadow loam) of different ages, the older of which is covered in places by an "Auen-Schwarzerde" (black meadow soil), probably formed during the postglacial climatic optimum. Twelve species of river molluscs were found and determined.
