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.
Kalmit
Since 2012 there has been a special facility on the Kalmit for measuring visibility; its task is to record visibility in the Palatine Forest-North Vosges Biosphere Reserve. Whilst at many, unmanned, weather stations, visibility measurements are made automatically for the range 0 to 10 km which is relevant to traffic safety, the measurement station on the Kalmit is designed for the range 10 to 390 km, which is relevant in assessing the fine dust content of the air. Measurements and survey photographs are obtainable through the "Fern-Sehen Project" ("Projekt Fern-Sehen") in the Palatine Forest, which is managed by the House of Sustainability in Johanniskreuz, a department of the Rhineland-Palatinate State Forestry Commission. Another feature is that the values were introduced to alert nature lovers, because exceptional visibility is very rare and difficult to forecast.
