The mud volcanoes in Wusu City of Tacheng Prefecture, Xinjiang, are precious geologic relics left by nature. In the unique and rare mud volcanoes, mud gushes out along the stratum channel of several kilometers, then flows slowly to lowland area, gradually forming a variety of landforms. The mud volcanoes are steep and precipitous, stretching for several kilometers. When mud erupts, it makes a "gurgling" bubble sound, which makes people feel the pulsation of the earth. Climbing up the stairs, you can see the unique scenery of rugged and bizarre mountains. The rocks are yellow, red, black, gray, green and of other colors, like a giant three-dimensional landscape painting, and people can't help but sigh the wonders of nature.
