Since the completion of California’s Crowley Lake reservoir in 1941, an intriguing enigma has puzzled observers – strange column-like formations on the reservoir’s eastern shore. These rising gray and stony cylinders, adorned with cracks spaced about one foot apart, have drawn comparisons to the grandeur of Moorish temples.
Such captivating descriptions naturally led to a multitude of theories regarding the origins of these peculiar columns. Some believed they were simply eroded rock formations, fortuitously carved into perfect spirals and arches over time. Others speculated a link to the area’s volcanic history.
To unravel the mystery, a team of geologists from the University of California, Berkeley embarked on a quest for answers. Employing various sophisticated techniques, such as X-ray analysis and electronic microscopes, they carefully examined samples of the columns. The groundbreaking findings revealed the presence of tiny spaces intricately cemented by erosion-resistant minerals. These spaces appear to be linked to a colossal volcanic explosion that occurred approximately 760,000 years ago.
According to scientists, this volcanic blast was a staggering 2,000 times more potent than the eruption of Mount Saint Helens and led to the formation of the Long Valley Caldera, which now cradles the Crowley reservoir.
The researchers propose that the columns formed due to the interaction of falling snow and the tuff rock deposits left behind after the ancient eruption. As the snow melted atop the still-heated porous material, it induced boiling, creating the evenly spaced gaps between the columns that we observe today.
Within a 2- to 3-square-mile area east of Crowley Lake, it is estimated that up to 5,000 of these striking columns exist. They appear in clusters of various shapes and sizes, some standing tall like gray poles, while others are bent or tilting with a reddish-orange hue. Additionally, several columns still remain buried beneath the surface, resembling fossils to an untrained eye.
With this geological revelation, the enigma of the Crowley Lake columns has finally been solved. These extraordinary formations stand as a testament to the mighty forces of nature that shaped our planet’s history, leaving behind an awe-inspiring legacy for us to marvel at and understand.
