Don’t forget that you are walking on a kind of powdery sand that is also called “grésou” or “a dolomic arena”. It’s simply the result of terminal erosion of the calcareous dolomite which on such unusual ground has created dry and untypical vegetation.
With a little luck, you might come across the delicate “arméria de Girard” flower. But here we are in the universe of the rosemary, the immortelle and multi-flora heather which flowers in the autumn!
Another way to observe this unusual calcareous rock is to take the little road between Mourèze and Salasc. Go through the ruin-shaped landscape seemingly less eroded than the Cirque’s, but which has many surprises all the same!
