cave window camp road end

The cave, which was probably a Japanese observation post, was where the camp road came closest to the ridge.  Looking at the image I wondered what the white area at the top was, but I remember that the cave's roof was very close to the ridge line and that it had at least one 'Dorman and Long' steel girder holding it up. Rather than being a cave it was possibly of a cut and cover construction.  (Andrew S)
