Lake Zaysan
A freshwater lake roughly 1,810 km2 in size, Lake Zaysan is located in eastern Kazakhstan, between the Tarbagatai and the Altai Mountains. In the region of East Kazakhstan, it is the biggest lake. The lake is 105 km long, 22–48 km broad, and has a maximum depth of 15 m. It is located at an altitude of 420 m.
Since Lake Baikal is 25–30 million years old, it is frequently referred to as the oldest lake in the world. Although its exact age is disputed and classified with some uncertainty, Lake Zaysan may be significantly older, potentially dating from the Cretaceous period and presumably older than 66 million years.
The Kiin Kirish valley and a portion of the Zaysan depression's coastlines are covered in comparable geological formations. The Zaysan depression is a tectonic intermountain depression located between the Zhonghar Altay mountains and the foothills of the Mongol Altai highlands.
Stopping at Zaisan lake while camping is exciting. A melodic ringing that sounds like wire hum can be heard in the evening when the sky is filled with stars. The lake's alternate name, "Lake of Bell Ringing," was given as a result of its distinctive sound. About 100 years ago, thousands of wild Bactrian camels, Przhevalsky horses, kulans, gazelles, saigas, bustards, and tigers lived here. You can still see bustards and other such creatures in this region now.
