Day 6: Sisteron and its clue

Go on an intimate discovery of the vertical strata that make up the Rocher de la Baume. Coming from limestone sediments deposited horizontally at the bottom of the sea at the end of the Jurassic, these layers folded twice: at the end of the secondary era-beginning of the Tertiary and during the alpine phases.

As you climb, look for ammonites embedded in the rock. Take the time to appreciate the scent of the clumps of wild thyme.

To find out more, discover the thematic sheet "The clues of Haute-Provence".

Climbing sites for all levels with more than 100 equipped lengths, a wide variety of levels (from 4 to 8) and types of climbs, all sectors are quickly accessible on foot.

La Baume site: the Rocher de la Baume is one of the most beautiful sites in the region. Renowned for the variety and multiplicity of its 100 routes, it is a rock-school allowing any climber, whatever his level, to achieve an ascent to his measure. From 4c to 5b.

Collet site: sheltered from the Mistral and suitable for young children. Small bar of rock 25 meters long by 5 to 6 meters high, made up of two parts separated by a weakness in the central part. From 4a to 8.

The clues of Haute-Provence
In the territory of Haute-Provence, the limestones of the late Jurassic are easily recognized; they form impressive massifs and rocky bars!

These deep valleys are either gorges or clues. The word "clue", which means "closed" in Latin, designates the constriction of a stream, a few hundred meters in length at most.

The hard limestone layers form natural barriers that are difficult to cross and the torrents take advantage of areas where the rock is fractured to cut its path.

The most famous clue is that of the Durance: the Sisteron clue. Guarded by the Citadel, it is strategic and marks the border between Provence and Dauphiné. Complete your knowledge with the “Earth and Time” course.

North of the Verdon gorges, many clues have been cut by rivers and low-alpine torrents: Clue de Barles, Clue de Chabrières, Sisteron or Bayons.
