Central South Australia is mainly desert today but 100 million years ago it was lush green forest around many interconnected lakes.
These days it's flat and barren with little or no life to be seen, the lakes are still there now as salt flats. Occasionally a dry river or creek will flood down from far off Queensland bringing fish, turtles and bird life to the countries centre. When this happens Australians and tourists alike flock to the lakes to see Pelicans and other sea birds breeding in unbelievable numbers.
The evaporation rate is far higher than any rainfall, so over time the lakes have concentrated salts from far off places. The salts are many metres deep and in fact the lakes are up to 15 metres below current sea levels.
Australia would be a very different place if the lakes were permanently full again….
This photo is actually Opal Fields, mining stretching back over 100 years.
