Small sector behind Cuvier Est, on a ridge parallel to the area Cuvier Rempart, about 200 m to the north of that area. A historic blue marked path leads through this area. The blue strokes are hardly visible. This path starts near the area La Reconnaissance, passes through the area Le Petit Rempart and ends in Cuvier Rempart near L’Aangle Alain.
Access: traverse the classical sector of Cuvier Est by La Route de Bellevue and continue up to the GR (about 150m). Follow the GR to the right for 100m up to square boulder on the left hand side of the path, just before a big bend to the right. The first problems of sector Proueptologue are 50m on the left up the hill. The problems of sector Caverne des Sorcières are 150m to the east from here. Take a small path to the left, 20m past the square boulder, which leads through a small valley. Turn right 50m further to find the abandoned blue path which leads to the first boulders.
