Crimpy little slab where the crux is possibly getting off the ground. Start on two marginal crimps and trust your feet. If you use the big rampy hold near the top it is easier. The right hand version used to get 7b, but since they added sand it is generally agreed that the start is easier, and now only gets 7a+, and the left, with the big hold, gets 7a.
Not a bad 7a+ for lightweight frames and small fingers. For me the key was matching the high crimp, moving the right hand far enough over to leave space for the left.

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.
