Mt.Ma'an (4288 m) is the highest mountain in the southwest edge of Sichuan Basin. It is situated to the south of the Dadu River. The geographic coordinates are: 28°58′N, 102°55′E. There are six peaks over 4000 m in elevation. Many quaternary glacial landforms in this mountain have been discovered. It's a typical example of fossil glacial landform in the east China. Its glacial stages are the last glaciation (Q 3 3) and the neoglaciation (Q 3 4). Mt. Ma'an and Mt. Luoji (4359 m) are similar in the fossil glacial landforms, but there are still some differences between them. For example, the ratio between the direct difference and the minus difference is different.
