context_page_description: At 1,493 metres the Feldberg in the Black Forest is the highest mountain in Baden-Württemberg, and the highest in Germany outside of the Alps. The local municipality of Feldberg was named after the mountain.
context_section_description: The mountain's bedrock of gneiss is around one billion years old. The Feldberg region was uplifted three times and then eroded again. What exists today can be called the "third Feldberg". The "first Feldberg" was formed in the Precambrian as part of an orogen and was then completely eroded away. The "second Feldberg" arose during the Devonian and Carboniferous, as part of the Variscan orogeny. It, too, was eroded away, and, during the Mesozoic and Early Triassic, beds of Bunter sandstone, Muschelkalk, Keuper, Lias, Dogger and Malm were deposited in the resulting sedimentation space. Some of these sediments are maritime deposits from intercontinental oceans; the others are of continental origin. The "third" and current Feldberg was formed during the Alpine orogeny in the Tertiary. Since then these sediments have been steadily removed through water processes and aeolian erosion, and today little but the bedrock remains.
