Ore Mountains, Czech Krušné Hory, German Erzgebirge, range of hills bounding the Bohemian Massif, extending 100 miles (160 km) along the German-Czech border, and reaching an average width of 25 miles (40 km). The Bohemian (southeastern) side of the range has a steep scarp face (2,000 to 2,500 feet [600 to 750 metres] high in places); the outer slope to the northwest is gradual. The highest summits, Klínovec (4,081 feet [1,244 metres]) on the Czech side and Fichtel Mountain (3,983 feet [1,214 metres]) on the German side, are in the centre of the range. Loučná (3,136 feet [956 metres]) is at the northeastern end and Špičák (3,658 feet [1,115 metres]) at the southwestern end. The name of this range rightly suggests the tradition of mineral wealth, worked by generations of small groups of craftsmen (gold and silver, lead and copper, tungsten [wolfram], and pitchblende).
The ores in the hills attracted medieval immigrant groups of German miners from the northwest, who, until their expulsion after World War II, gave the whole area a largely German character and tradition. To the original mining economy the Germans added forestry, furniture making, textile industries, and some farming. The main feature of settlement on both sides of the range was small-scale towns. After 1945 the almost wholly German population was supplanted by an almost wholly Czech one. Certain parts, such as the western extension into German territory, suffered large population losses. After World War II the uranium deposits at Jáchymov (then in Czechoslovakia) and Aue (then in East Germany) were developed. Large quantities of brown coal are mined around Chomutov and Most in the Bílina River valley, Czech Republic.
Road communications across the Ore Mountains are good. There are also railway routes, but the sinuous and frequently dead-end tracks on the Bohemian side show the obstacle posed by the great scarp face. The numerous mineral springs and winter sports resorts in the Ore Mountains have aided the development of the tourist industry.
