Nice and mostly quiet boulder, located just next to Croix St. Jerome parking. It contains a couple of great lines on it! Nice toe and heelhook action on this one, pretty cool problem! Regarding to bleau.info the boulder starts really low with a lying start (like in the video from Sarah Kuster).
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.
