Geology is the science that studies the various structures of the Earth. It aims to understand the history of these structures by studying their locations. With other related scientific disciplines, geology covers the composition, structure, history and evolution of the Earth's inner and outer layers. Geology also deals with the processes that shape the Earth. It can be likened to a type of alphabet, a code that allows us to read landscapes like the open pages of a book.
The history of the Earth can therefore be interpreted through the geology of an area, which is evidently the case along this trail, winding through a site of noteworthy complexity in terms of geological history.
Due to the extreme folding that the bedrock was subjected to at the Vissou, there is a chronological inversion of the topographical features: certain older limestone features are located above the more recent schist features. This extremely fascinating combination gave rise to a specific pattern of erosion, making it possible for intermettent water flows to infiltrate the various cracks.
