Westhessische Senke
The Neustadt Saddle is part of the Mediterranean-Mjøsa Zone, a sequence of valleys that runs from the Rhone valley along the Upper Rhine Graben, the Wetterau and the Gießen Basin, below the Anterior Vogelsberg to the Amöneburg Basin; from there via the Neustadt Saddle in the West Hesse Depression and on along the Leine Graben to the Oslo Graben.
