The waterfalls of Roquefort "Les Cascades" (Turning away from the route)

The Cascades produced a rare and very fragile phenomenon: a tufiére 30 meters high. True natural geological curiosity, the tufiére or petrifying waterfall is formed of pulverulent and friable limestone tuff of white to beige color. The water of the sources of the Turasse being particularly calcareous, the tufa is deposited on the mosses and the pieces of wood in the form of a crust. The disposition of these vegetable debris by fermentation gives in part to the rock its porous texture reminding that of the sponge.
