Warthe Stage

The Saale glaciation or Saale Glaciation, sometimes referred to as the Saalian glaciation, Saale cold period (German: Saale-Kaltzeit), Saale complex (Saale-Komplex) or Saale glacial stage (Saale-Glazial, colloquially also the Saale-Eiszeit or Saale-Zeit), covers the middle of the three large glaciations in Northern Europe and the northern parts of Eastern, Central and Western Europe by the Scandinavian Inland Ice Sheet between the older Elster glaciation and the younger Weichselian glaciation.

It succeeded the Holstein interglacial and was followed by the Eemian interglacial. The Saale complex is currently estimated, depending on the source, as existing from around 300,000 to 130,000 years ago or 347,000 to 128,000 years ago (duration: around 219,000 years), roughly contemporaneous with the glaciation of the Riss Glacial in the Alpine region. The actual "ice age" includes only part of the Saale glaciation or Saale complex. The first cold phase (Fuhne glacial) at the start of the Saale complexes is separated by a warmer period (Dömnitz interglacial) from the actual Saale "ice age". The term "Saale Ice Age" or "Saale Glacial" thus has 2 meanings in the literature - it sometimes refers to the phase in which the glacier advanced into North Germany, but can also refer to the whole Saale complex. The terms are frequently interchanged in the literature.

The Saale Glaciation occurred at around the same time as the Wolstonian Stage in the British Isles and the Illinoian Stage in North America.

The maximum advance of the ice sheet in North Germany during the Drenthe Stage is described by a line from Düsseldorf via Paderborn, Hamelin, Goslar, Eisleben, Zeitz and Meissen to Görlitz. From the eastern edge of the Harz eastwards (Poland, Brandenburg, Saxony and Saxony-Anhalt) the ice advanced to about 10 to 50 km behind the maximum extent of th Elster glaciation. On the northern edge of the Harz the two ice sheets reached the same line; and west of the Harz the ice of the Saale complex extended over 100 km further south than the ice sheet of the Elster. In front of this line, i.e. in front of the former glaciers, fluviatile and periglacial sediments are widespread. In the Drenthe Stage the present day North Sea basin, Great Britain and Ireland were also affected.
