Plateau de Millevaches
From Wikipedia, the free encyclopedia


The Plateau de Millevaches (French pronunciation: [plato də milvaʃ]; Occitan: Replanat de Miuvachas) is an upland area in Limousin a former administrative region of France. It covers approximately 3,500 km2 and crosses the boundaries of three French departments: Corrèze, Creuse, and Haute-Vienne.
The majority of the area is at an altitude of between 600 m and 1000 m.
Although commonly referred to as a plateau, the Millevaches Massif is actually more like a shallow dome, deeply dissected by streams and rivers, and slightly tilted, with the south-eastern edge elevated and more exposed. This is the visible remnant of a laccolith, a large lens-shaped mass of granite, believed to be the result of an intrusion of igneous material in the late Hercynian or Variscan orogeny.[1] As the surrounding, softer material has weathered away, the laccolith has become increasingly exposed.
Although not strictly a plateau, depending upon which direction one approaches the area from, the Plateau de Millevaches forms an important kind of step up (or a step down) in the Massif Central. There are a number of definite peaks, the highest being Mont Bessou (976m.), at the southern edge of the massif, near Meymac.
