The rocks of Baude

The rocks of Baude are made of thick limestone beds eroded on several levels, in rock shelters (balms). This limestone was formed about 130 million years ago in a warm, shallow sea, as in the Bahamas today. Many organic debris (shells, corals, etc.) have accumulated over huge layers to form the so-called Urgonian limestone. They occupy most of the Petit Luberon and most of the Vaucluse mountains.
