The mountains were formed in the Mesozoic, about 100 million years ago, when an ancient sea disappeared due to uplift. Later, in the Quaternary, the landscape was shaped by the influence of glaciers.
In many cases, stone pillar forests were formed. The vegetation of the area depends on altitude: Below 1,100 m, moist forest can be found; deciduous forest stretches from 1,100 m up to the tree line at 1,800 m; above that the vegetation consists of alpine grass-lands.
