A lonely block surrounded by lush green offers this cool roof and arete line. There are two possible ways to start the boulder: either move left underneath the roof and climb out again or directly move out left to the arete.
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.
