This is a fun variant on a popular but slow drying boulder. Please don't climb it if it's wet! Low sit start under the roof to the left, with both hands in the break. Climb the roof to the prow, and enjoy the traverse to the right which is easier if you're small! Exit with a mantle.
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.
