The Yangtze River runs through the whole area from west to east, covering a course of 665 km (413 mi), cutting through the Wu Mountains at three places and forming the well-known Three Gorges: the Qutang, the Wuxia and the Xiling gorges.[45] Coming from northwest and running through "the Jialing Lesser Three Gorges" of Libi, Wentang and Guanyin, the Jialing River joins the Yangtze in Chongqing.[46]
