Near the north bank of Kanas Lake, there is a long dead wood dyke more than one meter high and 2000-plus long. The dyke is formed of dead wood rolling down into the lake from Kanas Mountains. When lake water rises, the dead wood floats on lake surface at the foot of Youyifeng Mountain on the north bank; the lake water falls, the dead wood makes a thousand-m-long dead wood dyke. Why does the dead wood not float downstream with the water? It remains a mystery up to now. It is said that the dead wood is reluctant to part the Kanas as the native place for a long time.
