Pyramid-shaped mountains become hit online

Some mountains in Anlong County, southwest China's Guizhou Province,　have recently gone viral on the Internet. These visually sharp-edged mountains resemble the pyramids of Ancient Egypt.　

Professor Zhou Qiuwen, a geologist from Guizhou Normal University, explained that the mountains were naturally formed by the corrosion of limestone. The typical karst landform is a testament to nature's craftsmanship.　

According to Zhou, the vertical erosion by water has led to the original expansive rock masses being segmented into independent units. As this erosive process continues, the rocks at the top undergo significant dissolution, while those at the base are relatively less affected, resulting in sharp peaks atop wider bases.
