Yellowstone National Park, walking on the wilderness. (3)

We continued southward, saw yaks again, and had close contact with them. The mountains are still desolate, and the forests resemble Xinjiang. The clear river water reveals the blackness of the riverbed under the blue sky, making it impossible for the water to reflect the blue of the sky. It's like the torn chest of a giant. The water flowing down the hill seems to contain some substance, turning the riverbed white and yellow along the way. This reminds me of Huanglong in Sichuan, which is also golden all the way. However, where the water of Huanglong passes, it nourishes the growth of trees, while here, nothing grows. Alas, this Yellowstone National Park is just like its master, taking everything wherever it goes. Unlike our Huanglong, which nourishes all living things.
