Access Crack?

A low angle mostly thin crack that looks like it was the access point for the main ledge in years past. There is a single bolt at the top of the crack and there was a rotten old fixed rope there when I first saw it. With a good cleaning it would be a nice lil climb I think. As it is it's a little scrappy and filled with dirt and plants. Eventually I'm sure a proper anchor will be added on the ledge but for now you know what to expect anyway.  

Below the big right angling roof. This is the thin slabby crack to the left of the bolted line.
