storage area:- (#9 on the layout
only clue to what this area is are the large oil storage support
mounts on the ground. This oil storage area is constructed in
a 3-4 stepped concrete structure that goes up the slope like giant
steps. At each level I counted 4 oil storage support mounts, which
would equate to 2 large cylindrical oil tanks.
The bottom concrete step measured 70" in height.
