Demoiselles Coiffées: This exquisite cluster of some 50 spindly columns was formed by the erosion of a ravine below the mountain Pointe du Daillait. It is situated in Pontis, a village in the French Alps, and it remains the most impressive example of hoodoo geology in France. The phrase "demoiselles coiffées" translates to "ladies with hairdos"—a reference to the layers of hard rock (one of which is covered in vegetation) that are perched atop the tip of the tapered column's softer rock.
