Lake Amadeus
Lake Amadeus () is a huge salt lake in the southwest corner of the Northern Territory, in Australia. It is about  north of Uluṟu. The lake is 180 km long and 10 km wide. It is the largest salt lake in the Northern Territory. Because of the dryness of the area, the lake is usually a dry salt crust. When it rains enough, water flows through it towards the east. It eventually connects to the Finke River. Lake Amadeus holds up to 600 million tonnes of salt. The groundwater soaks into the ground, and the lake supports several reliable springs.
