The Rocher Rond (round rock) is a summit in the Dévoluy massif of the French Alps.

It is preceded to the north (north to south) by the Grand Ferrand (big Ferrand, 2761 metres), and the Tête des Vautes (Head of Vautes, 2188 metres), which is connected to the main body of the mountain by the Col du Charnier (Col of the House of Death, lit.

final resting place of the bodies or bones of the dead, 2103 metres), and the Plate Longue (long plateau or plate, 2383 metres), which is a pyramid of bare rock and generally regarded as a sub-summit of Rocher Rond.

[6] The western slope is almost exclusively exposed rock and cliffs, overlooking the Lac du Lauzon, and the summit massif is of the Santonian strata, whilst some of the surrounding mountains are of another Cretaceous strata, the Barremian.

[7] However, this lies on top of another rock strata, of the Neocomian era, which is exposed below the cliffs in a concave slope descending to the shore of the Lac du Lauzon.
