Here we walk on indigenous terrain formed by the Valensole area's goelogical conglomerate-deposits, (mixed, compacted deposits), which we can also see on our right.

These geological formations from the Quaternary period offer a relatively flat terrain where the Estoublaïsse river flows. This is where the eastern most dwellings and crops of the Municipal District of Estoublon are located.

The olive tree, the emblematic tree of Provence and a symbol of peace, has been cultivated here for centuries.
On our left, we can clearly see mountains with higher peaks.
They are made up of limestone and marl from the Secondary Era and form a series of layers of non-indigenous land pushed up from east to west.

The Estoublaïsse river has cut the surprising Trévans Gorges into the landscape.
