The Huangguoshu waterfall, one of the largest in China, is situated over the Baishui River, one of the headstreams of the Dabang River in the Zhenning Bouyei-Miao Autonomous County southwest of Guizhou. As part of the Yunnan-Guizhou Plateau, the terrain is carved by the mountains into many canyons, rapids and waterfalls. The bed of the Baishui River is like a staircase descending step by step, forming nine falls at each step, of which the Huangguoshu waterfall is the largest. The Huangguoshu Waterfall is 20 meters wide, sometimes as wide as 30-40 meters in the summer rainy season. Its pothole, pounded into existence by the falling waters in long years is called the Rhinoceros Pool. As the roaring river pours down from a height of 57 meters, it sends up myriads of sprays 100 meters high, which glitter like rainbows in the sunlight. The rapids here provide wide prospects for developing the rich power potential.
