Quite a few high elevation gravels were found in the upper and middle reaches of the Qingjiang River within Jianshi, Badong and Lichuan areas, west Hubei Province. The characteristics of these gravels suggest that they are probably the “high terrace” of the NNE-trending ancient drainage system. ESR dating of the high elevation gravels indicates that the gravels were formed between the early and middle Pleistocene （677±67）-（789±78） ka in the middle reaches of the Qingjiang River, and in the middle period of middle Pleistocene （371±37）-（551±55） ka in the upper reaches. The same geological background （last rapid uplift of the Tibetan Plateau） indicates that the phenomenon that the Yangtze River cut through the Three Gorges is probably attributed to the constantly attack from east to west, which, however, took place a bit earlier than things of the Qingjiang River.
