Demoiselles Coiffées de Pontis
The Demoiselles Coiffées de Pontis is a rock formation in Pontis, near Embrun in the French Alps, located on the edge of the Lac de Serre-Ponçon. The formation consists of a number of hoodoos, described as a "set of narrowly-tapered rock columns....topped with a large rock balanced neatly on the tip." In French, such structures are referred to as Demoiselles Coiffées.
It is one of the best-known and most attractive examples in France of the structure; an earlier commentator referred to them as "some fifty bizarre columns with hairdos."
The Tour de France will use the road past the Demoiselles Coiffées de Pontis on the last mountain stage of the 2017 tour.
