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
In the later Paleogene (34 to 23.8 million years ago) and Neogene (23.8 to 2.8 million years ago) and also in the Quaternary period (2.8 - 0.01 million years ago) erosion processes once more dominated. In particular, it was the weathering and removal processes that occurred during the various cold and warm periods that determined the final topographical shape of the Palatinate Forest. Characteristic of this is a system of deeply incised valleys, especially in the north and centre, diverse mountain shapes and bizarre rock formations.
