LES TAFFONI
20110 Belvédère-Campomoro
Presentation
Granite is fissured naturally. Water flowing along its fault lines results in the gradual rounding of its blocks and the accumulation of coarse sand. This fragmented granite retains water and in so doing alters the shape and form of the rock. When the sand is removed via erosion, all that is left are piles of rounded rocks, which together form a chaotic mass. To initiate the formation of a ?taffanu? (hole), aIl that is needed is for a crystal to become detached from a rock; this crystal then gets bigger as it hollows out a gap upwards. Water enriched with mineral salts, the wind (which accelerates evaporation) and alternating dry and wet periods are the main contributory agents in the formation of this natural phenomenon.
