The Palatine Watershed, the drainage divide between the Rhine (Upper Rhine) and Moselle (Middle Rhine) comes from the Sickingen Heights in the west and reaches the northern Palatine Forest immediately west and south of the city of Kaiserslautern where it turns southeast. From Johanniskreuz it runs initially southwards – passing the Eschkopf and Mosisberg to the west – and then bends southwest in the area of the Hortenkopf; in this direction it continues via Gräfenstein Castle, Lemberg and forester's lodge, "Forsthaus Hohe List", before finally leaving German soil at the "Erlenkopf" southeast of Eppenbrunn (see map). It follows various ridges that are interconnected and separate the river system of the Schwarzbach from all the other drainage systems mentioned here.
