Palatine Watershed
In the southern Palatine Forest, the German part of the Wasgau, the Palatine Watershed begins on the French border in the area of the Erlenkopf hill (473 m above NHN), where it is a continuation of the watershed in the northern Vosges. Always generally running from southwest to northeast it initially heads eastwards past Eppenbrunn and Pirmasens over the Großer Schiffelskopf () and reaches the region of Gräfenstein Land. From there it runs up the Hortenkopf () in the central Frankenweide. Several kilometres it passes through the hamlet of Johanniskreuz (), one of the highest settlements in the Palatine Forest. The watershed then reaches the area west of Waldleiningen in the Lower Frankenweide.
Palatinate Forest
At the beginning of the Palaeogene period of the Cenozoic era (66 to 23.8 million years ago) the formation of the Alps led to considerable tensions in the earth's crust, which, in their forelands to the north of the Alps, caused a bulge in the mantle and crust. At the apex of the arch so formed, there were considerable tensile stresses, so that the rock layers were stretched and about 35 million years ago, deep cracks and depressions in the earth's crust occurred (passive rifting). At the same time the sides of the newly created lowlands were uplifted, in the case of the Palatinate Forest, to a height of about 1000 metres.
