This is a short but fun one. Starting off with a sitstart and move along the crack. Few moves and you finish with a low mantle. Can be combined with a short traverse to Cascade 7a.
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.
