The Black Forest consists of a cover of sandstone on top of a core of gneiss and granites. Formerly it shared tectonic evolution with the nearby Vosges Mountains.
Black forest mountain range, SW Germany, extending 90 mi (145 km) between the Rhine and Neckar rivers. Feldberg is the highest (4,898 ft/1,493 m) peak. The range is covered by dark pine forests and cut by deep valleys and small lakes. The Danube and Neckar rivers rise there. Lumbering and woodworking are important economic activities. Orchards and cattle are found in the valleys; grains are grown in the highlands. The Black Forest is famous for its clock and toy industries (cuckoo clocks, music boxes). It is a year-round resort area, known for its winter sports and mineral springs; Baden-Baden and Freiburg are the chief cities.
