History of the Ruhr warm and cold weather. During the Drenthe Stadium of the Wolstonian Stage, an ice sheet over Northern Germany covered the Ruhr and reached as far as the northern hills of the Central Uplands. The shape of the middle and lower Ruhr valley is due to meltwaters and the powerful force of the ice. Meltwater from the glaciers flowed westwards through the Ruhr valley. Where Essen lies today, this flow was temporarily hindered by a barrier of ice and rocky debris, forming an enormous lake which filled the valley at Schwerte. Large areas of the Ruhr come under Prussian control. Ironworks
