Evidencia desde fotos satelitales de alta resolución de la existencia de acequias antiguas sobre el altiplano boliviano similar a los descrito por Platón

By J.M. Allen

Above left, the traditional grid of parallel canals on the rectangular, level plain of Atlantis. "And on the inland side of the city, channels were cut in straight lines, … and they transported also on boats the seasons' products, by cutting transverse passages from one channel to the next"…Plato

Above right, theoretical drawing showing how the grid of canals fits the rectangular Altiplano, with Pampa Aullagas at its centre where the city should be.

Enlargement. The parallel canals are approximately 550 to 600ft (167metres to 183metres) apart with intermediate canals 275 to 327ft (84 to 100 metres) apart.

Many of the ancient channels are barely visible at first

Enlargement begins to show them clearly

One can see the chequerboard pattern of transverse canals

Another system of wandering channels like canalised rivers crosses the straight canals and appears to link up a system of wells fed originally from the underground water table.

The canals are supplied by a system of wells connected by feeder canals

Detail of well supplying canal system. The well has an outer diameter of 200ft and the water level appears to be too low for the system to function today.

Detail of another well 200ft in diameter with close by, remains of straight channels.

Section of canalised river with wells feeding straight canals. Some of the canals are still in use today but the vast majority appear to be abandoned and the cultivations fallen into disuse. Recently, attempts have been made to expand the cultivation of quinoa in the region.
