Ruiniform chaos of Rajol

About 240 years, the Causses (limestone plateau*) were formed by the accumulation of marine sediments. The errection of the Pyrenees and the Alps provoked an uprising of the region and formed numerous cracks on the surface area. The streaming infiltrates there, sculping rocks by dissolution of limestone. The erosion is more or less active according to the resistance of rocks, that's why we observe ruiniform sculptures today.
