EIFEL

plateau region of western Germany, lying between the Rhine, the Mosel (French: Moselle), and the Luxembourg and Belgian frontiers. Continuous with the Ardennes and the Hohes Venn (French: Haute Fagnes) of Belgium, the German plateau falls into three sections: Schneifel or Schnee-Eifel, Hocheifel, and Voreifel. In the Schneifel (German: Snow Eifel), near the Belgian frontier, scrub and forest are common, with cultivation only on the richer soils. The Hocheifel (High Eifel), which includes the highest point in the plateau, Hohe Acht (2,451 feet ), is a dissected highland drained to the east by the Ahr River, which flows through a vine-growing region. The Voreifel (Fore-Eifel) slopes south to the Mosel, the tributaries of which dissect its smooth surface. Evidence of volcanic action can be seen in the explosion craters and small cones. Igneous rocks such as basalt, tuffs, and pumice are quarried in the area. The plateau from Bitburg to Cologne shows signs of ancient habitation; in the Middle Ages, iron, lead, and zinc were mined. The Maifeld was settled early by the Germans, and near Lake Laacher an abbey was founded in the 11th century. The current sparse population dates mainly from the clearing of the forest in medieval times, when monasteries and castles were established. The three-field and common-pasture systems still show the remains of this period. Scrub is still cut, burned, and planted with a rotation of rye, potatoes, oats, and 10 years' fallow. Holdings are small, and land is minutely divided. Metalworking industries have disappeared, and many people have emigrated since 1870 to the Ruhr and Aachen.
