entrances., although I remember there was something strange in one section where
we found a concreted gully drain that ran to nowhere, however that was not where
this eastern entrance appeared to be heading. One explanation I can think of to explain
where this entrance went is that it may have gone down to the lower level below this
tunnel complex that many witnesses talked about. These lower levels below these guns
were necessary for the efficient operation of these guns. The ammunition was hoisted
up on chain hoists as per the Mk VII gun pits on the northern face and also as per
the gun on top on neighbouring Mount Victoria, yet we are led to believe that it
was not needed for these guns - even though these were in a far more strategic place!
Who are these Officials trying to kid? 
Many witnesses spoke of these lower levels
and ammunition hoists. A few witnesses spoke of a tunnel that protruded out from
the main gun on the summit in an easterly direction and on page 313 in “Tunnel Vision
Refocused”, Martin has a copy of an undated Maritime Parks Board Map showing such
an extension to this gun pit. For this tunnel to remain underground when heading
in this direction would mean it would need to descend quite rapidly due to the bank
in front of the gun and when you consider the fall needed to do this, (about 1 ft
drop in every 3 ½ ft) I would say that where it ends on this map is where it enters
the next level down and hence why it shows an apparent dead end as evidently each
tunnel layer was shown on it’s own sheet. However, maybe this was only a “planned
tunnel” and it was eventually dug differently, as shown in both of Martin’s books,
the Ground Penetrating Radar returns indicate a turn to the south.
This in turn creates the possibility that maybe the entrance to the east comes from this tunnel? In various photos, I have observed more entrances being built further south, so if we continue this tunnel direction towards the south also, it does lead to some possible interesting conclusions....
Whilst examining all the photos, I had I noticed a couple of more peculiarities and
they are shown in the following photos: 
You’ll note the three arrows show what appears to be fresh dirt down the side of
hill. This appears in several photos dated around this time.
Note the difference the camera makes in these two photos and what appears to be a door on the entrance in the LH photo.
