Introduction to Aza Glacier: Aza Glacier is a marine glacier located in Zayu Nature Reserve. The snow line is only 4,600 meters above sea level. It faces the southwest and is about 20 kilometers long. Among them, the front part of the glacier penetrates into the primeval forest area for several kilometers, like a silver dragon passing through the "green ocean". Therefore, the Aza Glacier is also called the "Green Sea Glacier". Since the altitude difference from the end of the ditch to the top of the ditch is more than 6,000 meters, the same ditch has different weather conditions ten miles away, with all climate characteristics from subtropical to frigid zones.
