Harz (härts) [key], mountain range, northern Germany, extending c.60 mi (100 km) between the Elbe and Leine rivers. The rugged mountains were once densely forested. They culminate in Brocken peak (3,747 ft/1,142 m high). The region has good waterpower potential, and intensive uranium-ore prospecting began there after World War II. The Upper Harz has extensive wastelands and a severe, rainy climate. It is noted for its mineral deposits (especially silver). Gosler, Germany, is the chief town of the region, which also has some summer resorts. The Lower Harz has a mild climate. It is an agricultural region where grains and cattle are raised. Wernigerode, Germany, is the main town.
