This is what creates the stunning spinning effect. It has been located once again on the surface of the lake. The locals have seen this on various occasions, but it is actually an artificial overflow, also known as the Glory Hole. It was deliberately built by engineers in the 1950s as an alternative to the more common road surface. Used to control the flow of water from a dam or a dam. The artifacts decided to build the feature that looks like a sewer in the dam as the narrow gap between the rocks where the dam is located would have left the pipeline with nowhere to go. And now, Glory Hole has gained its reputation. In 2017, it attracted hundreds of spectators who came to watch the exciting spectacle of the opening of the “gate”. Lake Berryessa can hold about 52.1 billion gallons of water before the excess begins to flow into the overflow. It reached its full capacity for the first time after 11 years in 2018. It reopened in 2019 after a season of heavy rainfall, which reportedly attracted thousands of confused spectators.

Formally known as Darvaza Crater, the fire pit formed in the early 1970s when the ground collapsed during a Soviet gas drilling mission. The hole is 20 meters deep and 60 meters (190 feet) wide. It is located in the Karakum Desert, about 160 miles north of the capital Ashgabat. Scientists are said to have lit a fire in the giant hole to prevent the gas from spreading, and the fire has been burning ever since.
