After the Crowley Lake Reservoir in California was completed in 1941, people discovered strange columnar structures on the east coast of the water body. There were a lot of them, with more than 5,000 stone columns in an area of about 4 square kilometers. These stone pillars are regular and orderly. Against their background, the entire area looks like an ancient temple. However, the stone pillars are already 760,000 years old, so they have given people unlimited speculation.
Recent new research has found thatThe formation of these stone pillars should be related to a large volcanic eruption that occurred in the high area 760,000 years ago.
This volcanic eruption was so violent that it formed the Long Valley Crater, which is today's Crowley Reservoir, and then the snow cover eventually formed what it is today.
Although this statement does not satisfy everyone now, these stone pillars have made this place a tourist attraction!
