Lake five colors

Especially the "five colors" is that from time to time, the water in the lake changes color, becoming yellow, dark green, deep blue, but most of the time the water is rough and blue.

The second mystery lake is that neighboring ponds dry up periodically, and Lake five colors - no. Furthermore, it does not freeze even in frosty winters.

Professor Fan Xiao for many years engaged in the research of these places. The main explanation is the existence of the anti-freezing lake at the bottom of its hot springs, which is confirmed by periodically appear on the surface of air bubbles. However, for many dives to the bottom of the lake sources and has not been found. A possible reason for this is that the bottom of the lake is completely covered trunks of fallen trees.

Lake water is so pure that when immersed in it can be seen by 40 meters. After years of research, scientists have found an underwater cave, as well as the tunnel connecting the five colors with other lakes.
