A fun little hanging fridge-style block that starts way down in a hole. Climb on blocky quartzy holds either side of the overhanging block, and either make a dynamic move up to the jug in the groove, or use a high heel next to your left hand if you're super short. With the jug in your left hand cross over to take the good crimp with your right, match and make a straight-forward mantle to the top
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.
