The Dollberg is 695 m above sea level. NN is the highest mountain in Saarland and belongs to one of the prominent mountain ranges in the high forest. These stretch as ridges running from southwest to northeast from the Saar to the Rhine. The ridges consist of quartzite, which in turn has its origin in sandstone. This was finally transformed into quartzite by pressure and high temperatures during the folding of the mountains in the Devonian. Due to its hardness, it is comparatively weather-resistant. As the surrounding, softer rock was eroded, the quartzite deposits were preserved as ridges. A beautiful hiking destination and, as the highest "mountain" in Saarland, of course also a highlight here in the region. https://www.naturpark.org/natur-und-kultur/natur/geologie/geopunkte-devon-permokarbon-nonnweiler-und-zuesch/dollberg

Traveling to all 16 peaks in the federal states, it is very interesting to see how differently the states deal with their highest peaks. Perhaps the term "natural" fits quite well here

𝐆𝐞𝐬𝐜𝐡𝐢𝐜𝐡𝐭𝐞 𝐍𝐨𝐬𝐰𝐞𝐧𝐝𝐞𝐥𝐞𝐫 𝐒𝐞𝐞 The lake has a size of 6.6 ha. It was dammed in 1979 and is fed by the water of the Wahnbach. The Wahnbach, which rises near the Pascalhütte on the state border of Saarland and Rhineland-Palatinate near Steinberg, flows north of Büschfeld into the Prims. The reservoir is the heart of the 20-hectare leisure center of the same name. Due to the strong commitment of the local associations, which are organized in the local history and tourist association, catering by the lake and a well-filled calendar of events are guaranteed in the summer season.
