The Wasgau Felsenland (rock country) is rich in bizarre sandstone rock formations, which have been formed over the millennia by the weathering and erosion of strata of differing hardness belonging to the Lower and Middle Bunter (see Geology section). In the Palatine part of the Wasgau alone there are over 200 rock massifs and free-standing rock pinnacles. Depending on the erosion of the Trifels, Rehberg and Karlstal beds they are classified as rock terraces (Felsriffe, e. g. the Heidenpfeiler and Buhlsteinpfeiler near Busenberg; the Lämmerfelsen rocks near Dahn), rock faces (Felswände, e.g. the Asselstein near Annweiler; the Erbsenfelsen near Egelshardt) and rock walls (Felsmauern, e. g. the Dimberg near Dimbach). Other rock forms are pinnacles (Felstürme, e. g. the Hundsfelsen near Waldrohrbach; the Hühnerstein near Hauenstein) and blocks (Felsklötze, e. g. Lindelbrunn near Vorderweidenthal; Fleckenstein near Hirschthal and Lembach), which are mainly found on top of conical hills.
