Starting on the far left of the boulder with both hands to the left of the groove, climb down through the groove and under the belly of the rock on foot jams. Being small helps when you have to pass the rock underneath to pull onto the front face. A marginal heel-toe placement helps to gain height for a somewhat long move to the crimps on the arete.
I loved this route, and spent lots of time in this beautiful part of the forest. Three-dimensional roof climbing fun,
No Climbing Today!
Rain sucks, but broken holds suck even more. Remember, never climb on wet rock in Fontainebleau.
The sandstone becomes brittle, and pulling on it will ruin classic problems. Drying it doesn't help, because it's still wet and weak inside.
All you can do is wait for better conditions.
