Lake Issyk
The Lake Issyk also known as Issyk Lake (, "Esık kölı") is a lake in Kazakhstan fed by the Issyk River. It should not be confused with the Issyk-Kul Lake in neighboring Kyrgyzstan. History. It is estimated that the lake was formed about 8-10 millennia ago, as a result of a catastrophic earthquake that caused the collapse of the right slope of the gorge. After the collapse, debris blocked the gorge and created a dam about 300 meters tall. A lake formed behind the dam was about 1,850 meters long, 500 meters wide and 50 to 79  meters deep, located at an altitude of 1,756 meters. The lake became known in Russia and Europe by the middle of the 19th Century, after the formation of the village of Nadezhdinskaya at the mouth of the gorge. One of the first researchers was the geographer Semenov Tien-Shansky, who mentioned the lake in his diaries: "we were delighted to see at our feet the "Green lake" (in Kazakh "Jasyl-Kol"), which had the purest and most transparent, thick bluish-green color of the TRANS-Baikal beryl. Beyond the lake rose a bold and steep jagged ridge of high squirrel  ... this mountain the guide called Issyk-bash." The Caspian tiger was found in the Issyk gorge and around the lake at least at the beginning of the 1900s and is mentioned in the diaries of Pyotr Semyonov-Tyan-Shansky. The lake is mostly famous for the way it was created (an ancient natural landslide damming a valley), destroyed (another natural landslide destroying that dam in 1963, with a subsequent flood damaging the city of Esik), and re-created (with human help). In 2019, the road surface was restored at the dam and parking was organized right on the ridge. Infrastructure  for camping has been created, gazebos, tables and benches have been built, fireplaces have been organized.
