Description :

The elusiveness of dinosaurs! Even if you know how and where to look at the rugged landscape where their former presence shows on the surface, you’ll still need a very sharp sense of observation and lots of patience to be able to follow in their footsteps. All along this little jaunt (“Petite vadrouille”), you’ll take a stroll back in time through the history of the earth in their presence.

Descriptif détaillé :

Cairns (1) and (2) The landscape offers a succession of parallel layers, laid-out over the ages at the bottom of the ocean. Each layer belongs to a different “storey” of the geological era. With each new layer, we get closer to the present day. The most ancient “storeys” visible here date back to the era of the dinosaurs.
Cairn (3) At the end of the Mesozoic era, the climate is extremely hot and humid, a bit “like Africa”. The reddish soil dates back to this period in time.
Cairn (4) We are here where once used to be a lake (about 70 million years ago): the sediment which has been piled up has shaped the limestone ridge which is now in front of you.
Cairn (5) The “Laurio” stream, tightly embraced by the gorges, is of recent formation (early Quaternary period).
Cairns (6) (7) and (8) During the Tertiary, the Pyrenees are shaped, causing massive erosion.
The materials are carried off by the torrents. These days, ‘puddingstone’, pebbles agglomerated in limestone, can still be found in the riverbed.
Cairn (9) Above the path, the Saint-Romain chapel, was renowned for its capacities of healing children from muteness.
Cairn (10) In the limestone, numerous fossilized “foraminifera” can be found. These are unicellular shell-like creatures which could be the size of a small coin.
Cairns (11) and (12) Lichen lives on the surface of rocks. This species of composite organisms, formed by the marriage between fungi and algae, can colonize those environments on earth which are most unfit for life. People have made use of these rocks for their constructions.
Cairns (13) and (14) 40 million years ago, this area is part of a “gulf” which slowly gets filled in by the materials deposited by the currents. The roughest of these river deposits, the ‘puddingstones’, which have been carried by the fiercest of currents, can be easily distinguished from the path.
Cairn (15) Just above you, the Lacamp plateau is situated. It is occupied by flocks of sheep.
Cairn (16) This area, devoid of all vegetation, is called a firebreak. Its purpose is to slow down any eventual progression of fires.
