Saint-Jacques, the end of the Luberon

In the distance, the Saint-Jacques hill emerges from the plains, overlooking the town of Cavaillon. This is actually the continuation of the Petit Luberon massif, formed by the same limestone but separated from it by a gap created there over 30 million years after two rifts caved in. One of the two is the Salon - Cavaillon - Fontaine-de-Vaucluse rift. This is a major and active rift, with an important role in the geological history of Provence.
