Another great line at Apremont Désert. The boulder is just behind the famous ‘Pilier du Désert’ and has a nice pinch hold in the middle. The sit start is a bit trickier than it looks at first sight.
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.
