The complete southern half of the volcano is missing.

Above, oblique view showing reconstruction of probable position of walls in relation to rings of land and channels
according to the scheme of Plato.
The cities of Susa and Ecbatana in Persia had similar concentric walls on battlements,
the inner ones higher than the outer and painted in different colours with gold and silver in the centre.

Above, oblique view from north showing the cross-like qualities of the site formed by the opening up of two bays, probably due to earthquakes.
The inner channel shown here is now higher up the mountain suggesting that this part of the volcano was pushed up later.

Above, view of summit or Acropolis from the south showing how the central island or Acropolis faces towards the south and is sheltered from the north by the rim of the volcano.

Above, view from the northern rim looking south. Plato: "This part of the island looked towards the south and was sheltered from the north".

Above, view from the south showing the embankment faced with stones behind the village. I suspect this has become detached from the main body of the volcano due to earthquakes and forced outwards creating the sandy channel seen on the inside so that the wall of stone shown here would have been continuous instead of appearing broken off as it does at present.
Geological studies are necessary to establish what the original shape of the volcano may have been, which parts may have sunk or risen and which parts may have become detached from their original locations.

Above, this section of the embankment behind the village is still covered in katawi - fossilised lake deposits from the time it was under the sea (lake Poopo).

Some people call the white material coral, the local name is "katawi" - fossilised lake deposits from the time it was under the sea (lake Poopo).

Above, ground view of the above ribbon of stone clinging to face of volcano.
The other stones which would have been covered in the white katawi have fallen away and disappeared beneath the ground.

The remainder of the original outer stone from the volcano has fallen away and disappeared beneath the ground.

Above, oblique view showing outer ring of water 3 x stades of 100 cubits wide and the channel from the sea which pierced the outermost ring of rock.
Plato: "beginning at the sea, they bored a channel right through to the outermost circle, which was three plethra in breadth, one hundred feet in depth, and fifty stades in length; and thus they made the entrance to it from the sea like that to a harbor by opening out a mouth large enough for the greatest ships to sail through." (115d)

Above, oblique view measuring the channel though the outermost ring, reported as 3 x plethra = 3 x 110ft = 330ft (Sumerian Units).

Above, oblique view measuring the outermost water channel 3 x stades of 100 cubits wide.
Plato: "The greatest of the circles into which a boring was made for the sea was three stades in breadth."
