An unexplored shaft in the track. At this point the tracks runs over a sandstone bed some metres thick. A large block of this has slipped away towards the adjacent depression leaving a slip rift feature. This is open to the surface at one point in the side of the track where it is possible to see a short distance down and along the rift in both directions. This is all in sandstone.
