Wuhua Hai (Five-Flower Lake) is regarded as the most beautiful lake of the Jiuzhaigon NationalPark. An this national park is rich in lakes, it has the legendary 108 haizi (literal son of the sea,meaning multicolored lakes). Those lakes were, according to legend, created by an ancient Goddess who dropped a mirror her lover hadgiven her. It broke into 108 pieces which became those colourful lakes.
The lake is rather shallow and has a unique colour of different shades of turquoise. The floor is littered with fallen ancient tree trunks, the floor between the truncs and plants purewhite. The colour is caused by the high amount of soluted limestone, a typical thing in karst area. The water absorbs the sunlight, but the blue part of it is less affected. As a reult the water becomes a blue filter and the colour is best seen in sunshine.
The fact that there are so many lakes is actually also a result of the karst. The limestone which is soluted in the water deposits in the bed of the river an causes the white limstonedeposit on the ground. It also covers plants and trees and form dams of sweetwater limestone or tufa, also called travertine. Those dams or rimstones form series of pools conected by waterfalls or rapids. The most impressive dams are the Pearl Shoal Waterfall, which is 310m wide, and the NuorilangFalls which are 320m wide.
Jiuzhaigon National Park is a high-altitude karst (~2,500m asl) shaped by glacial, hydrologicaland tectonic activity. The rocks are mostly dolomite and limestone, but there are also sandstone and shales.
