This adds a sitstart to a simply beautiful piece of rock. The first move is tricky if you're short, but the placement of the right foot makes a lot of difference. The pendulum moves with the feet are so satisfying on the upper section!

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.
