Start from the ground (without crash-pad) in front of the small block at the foot of the prow, climb the prow (without the large pockets from Le Trou de Secours (white n°7) on the right), take a crimp/oinch in the face on the right and an undercling on the left (without touching the block on the left) and exit directly with the arete left hand and slopers on the edge.
NB: the boulder is well exposed to the sun, especially in the afternoon, but due to its shape, the holds remain wet for a long time (especially the undercling left hand and the large ball), only attempt it in very dry weather; the first ascent was made with a knee pad.
