Sakt Flats
|
The salt flats in Badwater Basin cover nearly 200 square miles, among the largest protected salt flats in the world.
Three basic things are needed for salt flats to form:
* source of salts, usually from a large drainage system
* enclosed basin that doesn't drain to the sea and wash away the salts
* arid climate where evaporation exceeds precipitation, leaving behind just the salts and fine silt
