Here is the view from the same spot, but in the other direction looking deeper into the tunnel. You can see the floor is covered in thick, sticky mud, but there is only a short stretch of water along towards the end of the tunnel. On the left wall near the camera you can see the channel that looked as though it held electrical cables.
Half-way along on the right wall is a low tunnel branching off to the right, with its ceiling sloping slightly downwards towards us. At the back of this photo is another low tunnel with a sloping roof. There is also a larger doorway in the right wall at the back of this photo, though it cannot be seen here.
