There is a map showing where the photos were taken - including the direction - though this is not always accurate! There is also a map showing the possible area of the quarry - though the south east enge is indeterminate,
The height difference between the river bed (photo 13) and the land to the west above the quarry (photo 21) is some 13.9 metres (45.6 ft) which gives an idea of the western rock face and the infill below this face.
The southern end of the quarry is indeterminate. At the eastern side it tapers out gradually but on the western edge there is some evidence that it may have continued to the road and slightly beyond.
