goes on for miles

Twice submerged by a large high-altitude lake, the salt flats now cover a total area of over 12000 square km (7440 square miles) and today serve as one of the country’s main salt mining centres. The last large lake dried up about 8000 years ago, leaving the small lakes of Poopó and Ururu, as well as the salt flats of Uyuni.
