On a big boulder near the crest, 200m before Accelerator when coming from the parking lot of Rocher Gréau. Start in the slab to the right of Stonemason and exit with the arete left hand.
Caution (January 2020) : the second hold has broken off and the stone is flaking on the whole boulder...
A 5+ direct exit was climbed by Hunter Damiani in december 2024 after more holds broke.
