The first pass of Sichuan-Tibet railway: Zheduo Mountain

Zheduo Mountain is located in Ganzi Prefecture, Sichuan Province, with the highest elevation of 4,298 meters. It is called the first level of Kangba. There is a saying circulating in the local area, which is called "Erlang Mountain, which scares people to death, and Zheduo Mountain". This shows how high the mountain is and how difficult it is to climb it.

At the same time, Zheduo Mountain also has important geographical significance. It is the most important traffic artery on the Sichuan-Tibet line. "Zheduo" means bending in Tibetan. To the west of Zheduo Mountain is a plateau uplift, with Yalong River, alpine canyon and Dadu River on the right, and to the east of Zheduo Mountain is a mountainous area, and to the west is the eastern part of Qinghai-Tibet Plateau, which is a real Tibetan area. Moreover, another performance of "folding more" is that the mountainous Panshan Highway can be called nine bends and eighteen bends, which is really folding more.

The highest elevation of Zheduo Mountain is Zheduo Mountain Pass, which is formed by "traceable erosion" with glaciers as the main feature. It is said that during the last ice age of 1, 000 years ago, most of the mountains in Zheduo Mountain were once covered with snow and ice, and the glacier tongue of some glaciers also reached the valley near 3000 meters above sea level. When the geological history entered about 65438+2000 years ago, the earth's climate suddenly entered a continuous high temperature stage, and the snow on Zheduo Mountain also melted continuously, and the glaciers in the valley melted rapidly. Some glacial meltwater that could not flow away in time stayed in some lakes, leaving a lot of moraine deposits.

No matter how professional you are, it is not easy to climb the first pass of Kangba at an altitude of 4298 meters-Zheduo Mountain. But when you climb the winding mountain road step by step, seeing the scenery along the way and breathing fresh air will always inspire you to keep heading for the highest altitude. However, in this process, you will be exhausted several times because of altitude sickness, but when you finally climb to the top of the mountain and see the elegant sea of clouds and vast snow-capped mountains, you will be proud of your persistence and feel that all the difficulties encountered along the way are worth it.
