The identification results through micropolariscope and X-ray fluorescence spectrometer reveal that bedrock of pits is from middle to fine-grained moyite being apt to be weathered and modified. Based on field investigation and periglacial geomorphic theory, the pits on top of Shigujian Peak are attributed to freezing-thawing of periglacial action. Meanwhile, storm and strong wind accelerate the process. Observation shows that both the actions are still undergoing and variant directions of wind are the main cause for making different shapes of the pits. Because the top of Shigujian is 1500 m lower than the present snow line, some scholars considered that "glacial pothole" formed in the Quaternary is hard to work, even though in the Last Glacial Maximum (LGM)
