Hillside in the east Panda Lake is abrupt with frequent land fallings and its base rock is exposed. The stone cone formed by falling of rock is well developed and is in large scale. However, the vale of the valley is very narrow and blocked channel shaped by falling rocks forms the 65 m high moraine dam. Accumulated water of blocked channel of moraine dam forms the Panda Haizi; the water of the Panda Haizi passes over the stone dam to form the high waterfall. Even though the front edge and craggedness of the waterfall experienced anaphase calcification and it is coved by large amount of falling sediments, it could still be made out the vestige of the accumulated falling rocks.
