, about 22,000 to 18,000 years ago, and the end of the glaciation in North Germany about 14,500 years ago. At that time the glacier was melting and the waters attempted to find their way to the lowest lying points. The Elbe Urstromtal collected the meltwaters and carried them to the

, which then lay up to 120 meters below its present level. The then coastline was about further north. The Elbe Urstromtal also collected the meltwaters of the three ''urstromtäler'', the Glogau-Baruth Urstromtal, Warsaw-Berlin Urstromtal and Thorn- Eberswald Urstromtal and carried them in the direction of the North Sea Basin.
