To find the location of Atlantis, it is only necessary to follow three steps from Plato.

Step 2. Midway along the longest coastline of this island, there is a smooth and level rectangular shaped plain, enclosed by mountains and high above the level of the Ocean sea. That is the Altiplano.

Step 3. In the centre of this plain, at a distance of 50 stades from an inland sea, a mountain sunk by earthquakes and floods and with concentric channels created by the god, Poseidon. That is the mountain of Atlantis, located at Pampa Aullagas.

Step 1. The island larger than Libya and Asia together.

Step 2. The rectangular plain midway along the longest coastliine

Step 3. The mountain destroyed by earthquakes 50 stades from the sea.
It was not the island as large as Libya and Asia together which sank into the sea, only the small volcanic island of the same name which sank into the inland sea called Lake Poopo, formerly, Lake Tauca.
