Million-year-old "pyramid" mountain attracts visitors, netizens compete to guess its origin

In recent years, An Long County in Guizhou Province (China) has become a popular tourist destination, thanks in no small part to its pyramid-shaped mountains.

In addition to their pyramid-like shape, these mountains also have layers of rocks stacked so neatly that anyone would think they were man-made.

Since photos and videos of the "An Long pyramids" went viral online around 2018, many theories about their origins have been put forward.

However, according to experts, these mountain ranges are completely natural.

According to Chu Thu Van, a professor at Guizhou Normal University, the mountains in An Long are typical of karst terrain.

Karst topography is a natural phenomenon of nature, a weathering phenomenon typical of limestone mountains eroded by running water. Conical mountains are the result of the weathering process of rock masses.

Professor Chu explained that vertical erosion caused by water caused the originally expanded rocks to split into independent blocks. As this process continued, the rocks on top were significantly eroded, while the rocks on the bottom were less affected. This resulted in sharp peaks and wider bases.

According to Mr. Chu, the mountains in Guizhou are made up of dolomite rock that is more than 200 million years old, from a time when the area was almost submerged in water.

Despite scientific explanations, many people continue to speculate about the origin of the "An Long pyramids", claiming that they are ancient tombs of an ancient civilization, prototypes of real pyramids, or the work of aliens.
