Crowley Lake Columns: Mysterious Volcanic Formations

After the Crowley Lake reservoir in California was completed in 1941, some column-like formations with cracks ringing around them were spotted on the eastern shore. Naturally, several theories arose on the origins of these columns. Some put forward the idea that the Crowley Lake columns were the result of volcanic activity. On the other hand, some others thought the wind or water eroded the stone to form these rising spirals.
