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 ("ladies with hats"), or more often Cheminées de Fées ("fairy chimneys"). In Théus, there is a concentration referred to as La Salle de Bal des Demoiselles Coiffées ("the ballroom of ladies with hats"), although these structures also exist in isolation. Two other significant sites exist 1 kilometer away on a mountainside near Remollon.
