Introduction to the wonders of glaciers: Near the north slope of Tanggula Mountain, there are mainly horizontal valley glaciers and hanging glaciers. The end of the hanging glacier ice tongue is often as high as 5,700 meters. There are two glaciers lying in the canyon on the north and south sides, pouring down, with steep ice walls and light and dark cracks, which are extremely dangerous and strange and spectacular. The snow line in this area is also higher than other areas, reaching over 5,800 meters.
