Earth and sky are indistinguishable on the Salar de Uyuni, a vast salt flat in southwest Bolivia.
玻利维亚西南部的乌尤尼盐沼的天与地浑然一体。
A great lake covered this area 16,000 years ago.
这个大湖覆盖在这面土地上已有16000年。
When it dried up, it left a 4,000-square-mile basin of salt, the world's largest such deposit.

It's also one of Earth's flattest places—relief varies by less than 16 inches.
这里也是世界上最平坦的地方——高差不超过16英寸。I
