This is a shortie testpiece!Little ones get an extra bonus in the form of a big throw to the lip from the weird crimps that start this fun problem. And everybody gets to do the full-value, full-commitment mantle that gets you on top of the boulder.
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.
