Local anomalies. Russia

In May 1938, geologist Igor Solovyov worked in Kamchatka, studying active volcanoes. One of the routes took Igor and his partner Nikolai Melnikov to the shore of the lake. Then it was marked on the map under a different name - the Big Coliger.

Geologists have not found any trails, even those trodden by animals. The animals avoided the lake for some reason, although large fish splashed in the water. People had to walk along the shore waist-deep in water, bypassing the hanging tops of the alder. The weather was sunny. The water warmed up, causing a minimum of trouble.

 - I saw a rock near which the alder did not grow, - Solovyov recalled. "There was a cave in it. Thinking that it would be possible to dry off and rest there, I bent over and entered it. Raising his head, he saw that the cave was flooded with water. In the depths, a rocky black island could be seen, in the middle of which a bright blue-white glow was spreading. I watched for about two minutes, and when I heard Melnikov's footsteps behind me and looked back, I was plunged into darkness. I realized that I was blind. Falling into the water, he screamed heart-rendingly: "Nikolai! Help me! Melnikov grabbed me by the arms and dragged me to the exit. For more than a kilometer, waist-deep in water, he carried me on his shoulders.

 The unfortunate geologist lay on the shore for 10 hours before some jumping white, green and yellow spots began to flash before his eyes. After another hour, my vision began to gradually return. Nikolai also saw the glow, but not for long, just a couple of seconds. This saved him from temporary blindness.
