Introduction to the glacier viewing area: The glacier viewing area covers an area of ​​15 square kilometers, with a large area of ​​alpine rhododendrons, purple birch and white birch as the main characteristic landscape, including glaciers, Fangmagou, Baishi Cave, double view platform, rhododendron Mountains, larch forests, etc. Due to the cold terrain, the valley began to freeze in early October, and streams continued to flow and freeze on the ice. Throughout the winter, canyon glaciers stretching hundreds of meters were formed here, with the thickest part of the ice reaching 4 meters. In April of the following year, the ice began to melt slowly, and thick remaining ice could still be seen until early July.
