Great line on an isolated block with great views. Starts with good holds, traversing right the holds become smaller. Precise left heels can help to move to the right arete and up from there.

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.
