Chengdu is located in the west of Sichuan Basin. Due to the huge vertical height difference, Chengdu has formed a unique landform type of three-point plain, three-point hill and three-point mountain. From Chengdu to Gongga Mountain, the terrain gradually rises, and the main peak of Gongga Mountain stands at the top of the peaks, with an altitude of 7556 meters, which is the highest peak in Sichuan Province. In good weather conditions, it is entirely possible to see Gongga Snow Mountain.

Extended data:

The climate in Gongga Mountain area is deeply influenced by altitude. Temperature decreases with the elevation, while precipitation increases with the elevation. According to the analysis of observation data for many years, the average annual temperature in Dongpo is 0.67℃/ 100 m, and the annual precipitation gradient is 67.5 mm/100 m, that is, every elevation increase 100 m, the temperature decreases by 0.67℃ and the precipitation increases by 67.5 mm. ..

The precipitation gradient above 3000 meters above sea level may fluctuate, but the annual precipitation on the snow line may reach 3000 mm, still showing an increasing trend.
