PLATEAU DU THAURAC
The Thaurac massif is a triangular plateau, isolated between the cretaceous basins of Ganges and of Montoulieu. It stands out 200 m above the vineyards thanks to its vertical rochy faces, stopped by the channel in which the Hérault river flows. It peaks at 487 m above sea level in the 'Bosc du grand Serre'. Despite the deep notch that this river imposes him, it continues towards the southwest in a clearly individualised unit; the 'Rocher de Sion' ('Sion's Rock') is its principal site. This isolated sector is frequently named 'Montagne d'Agonès' (The Agonès Mountain) by the potholers. Flaked in its northeastern part, it is deeply notched by limestone pavements: their very developed form gives access to numerous cavities, including the best known among them, the 'Grotte des Demoiselles'.
