Geomorphology

Morvan prolongs the Massif Central in the Northeast.  There is 300 million years, it was up to the Hercynian mountain ranges which have been flatened by erosion and buried under maritime sediments.

It was raised during the upheaval of the Alps during the Tertiary.  This uprising was more important for the South, as the old crystalline massif peaks at 901 meters, than in the North, where it comes down to 350 meters.  The resumption of the erosion then cleared it of its sedimentary coverage.

Morvan breaks down into three entities: . Opened Morvan
. High Morvan of hills
. The morvandelle mountain

Opened Morvan

 Characterized by a smooth relief and a hedged farmland, the north part of the granitic massif constitutes a transition zone with the calcareous plateau of Auxerrois and the marly lands of Auxois.

Two natural regions compose it: Vézelien in the Northwest and the low-Morvan in the Northeast.

Landscape of opened Morvan

High Morvan of hills
 Center of the ancient massif, high Morvan of hills presents a more emphasised relief and denser forest coverage, interrupted by streams and rivers giving rise to numerous ponds and man-made lakes.

The morvandelle mountain
Massive rounded tops with strong slopes cut into by narrow valleys give a mountain aspect to the South of Morvan.
