Geography
18,000 years ago, just after the end of the Last Glacial Maximum, the lake level of Lake Qinghai was around 30 metres lower than today. Between 15,600 and 10,700 years ago, lake levels secularly increased to around 10 metres lower than the present lake level, after which they declined slightly until around 9,200 years ago, when they began to rise again. Around 5,900 years ago, lake levels reached a peak of a few metres higher than today, before declining again amidst a regional cooling and drying trend until 1,400 years ago, when they were less than 10 metres lower than average modern levels. They then began to rise once more until reaching their present level.
