This other worldly landscape is actually Dagze Co, one of many inland lakes in Tibet. In glacial times, the region was considerably wetter, and lakes were correspondingly much larger, as evidenced by the numerous fossil shorelines that circle the lake and attest to the presence of a previously larger, deeper lake. Over millennia changes in climate.
Good site, Amazing Pictures from NASA.
