The climate has changed from wet to arid over the last 60 million years. Most of the rivers in the Lake Eyre basin are now slow flowing, flat and completely dry for lengthy periods. They all flow towards the lowest point in the basin, 16 metres below sea level, at Lake Eyre. Significant mineral deposits can be found in the basin.
