An unusual phenomenon was recorded in Berryessa Lake, which is located in the Napa Valley, California. A 22-meter funnel formed in the lake, which was dubbed the “Hell’s Gate”.
As inform mir24, this seemingly mysterious phenomenon has a simple explanation. A tunnel was built in a California lake in the 1950s, which is 22 meters wide and 75 meters long. It opens when the lake level exceeds 4,7 meters, acting as a drainage hole in such cases, which is capable of receiving approximately 1360 cubic meters of water per second.
The tunnel has already been opened in 2018 and 2019 and thus attracted the attention of eyewitnesses. In both cases, the reason for the opening of the tunnel and the emergence of a water funnel was the rise in water levels due to heavy seasonal rains.
